  Aim: To assess the prevalence of sexual difficulties and related distress, the association between sexual difficulties and sexual avoidance, and to establish whether sexual difficulties and sexual avoidance are moderated by relationship satisfaction. Methods: This study included a sample of 4,160 adults aged 18–89 years enrolled from a randomly selected web panel of 11,685 Norwegians. Results: Sexual difficulties were particularly common among adults aged <30 years. In men and women lack of interest in sex and general sexual distress were associated with more sexual avoidance. The association between lack of sexual interest and sexual avoidance was, however, buffered by relationship satisfaction. Climaxing too early was related to less sexual avoidance in both genders. Yet for men, this association was only significant among those with lower relationship satisfaction. Conclusion: The findings underline the important links among specific sexual difficulties, sexual distress, and the frequency of avoiding sexual activity.

  Objectives. The study explored characteristics associated with self-assessed effects of pornography use on one’s personal sex life. Methods. Survey data were collected in a probability-based sample of Norwegian adults (n = 4,160). Results. For most participants (41.3%) pornography had no effect on their sex life. More participants reported positive (33.2%) than mixed/negative (25.5%) effect of pornography use. Sociodemographic and sexual characteristics that predict these self-assessments were examined. Among participants in a steady relationship, indicators of relationship quality were unrelated to self-assessed effects of pornography use. Conclusions. The current study findings add to scant literature about self-assessed effects of pornography usage.

  Aim: This study describes the use of contraception and protection for sexually transmitted infections (STIs) in six different birth cohorts of the general population in Norway. Methods: The results are based on a 2020 national web panel survey among 18–89 year-olds in Norway (n = 4,160). Results: For respondents born within 1931–1950 versus those born within 1990–2002, there was a significant increase in the use of protection against unwanted pregnancy and STIs during sexual intercourse, and a significant drop in the proportion of those who did not use any protection at all. More women today (than in previous decades) are using hormonal contraception. The main reason for not using condoms during intercourse was both parties felt safe that they were healthy, especially those born within 1990–2002. Conclusion: To prevent unwanted pregnancy and STIs, it is beneficial to continue to increase the availability of free or subsidized hormonal contraception, including emergency contraception, and free condoms in public arenas that people frequent and where they meet their partners.

  Purpose: To study different subgroups of Norwegians’ frequency of sexual intercourse and the activities that Norwegians engage in during intercourse. Methods: Data were collected from a questionnaire survey of a representative web sample of 4,160 Norwegians aged 18 to 89 years. The response rate was 35%. Results: The majority of men (65%) and women (61%) reported sexual intercourse activity during the past month, and it was most common to report such activity 2 or 3 times per month. Partnered participants most often reported having intercourse weekly. The intercourse frequency of 2 to 3 times per week declined from 35% in participants aged 18 to 29 years to 8% in participants 60 years and older. The most common heterosexual activities reported were vaginal sex, stimulated genitals with the hands or mouth, use of sex toys, and anal sex. Younger and middle-aged Lesbian, Gay, Bisexual, Transgender/Transsexual, Intersex, Asexual [LGBTIA] men most often reported activities such as mutual masturbation, oral sex, and anal sex. Younger and middle-aged LGBTIA women most frequently reported mutual masturbation, vaginal sex, and oral sex. Conclusion: There seems to be a generational shift in types of activities in participants 59 years or younger, and those 60 years and above.

  Aim: This study explores the European North-South differences in older partnered individuals’ silencing of the sexual self and its links to relational and individual well-being. Methods: A web survey was conducted among partnered individuals aged 65 years or above in Norway and Croatia. There were 368 (women: 37.8%, response rate: 22%) and 359 (women: 34.5%, response rate: 27%) individuals who participated in Norway and Croatia, respectively. A range of relational (sexual satisfaction, relationship quality) and individual well-being (anxiety, depression, and life satisfaction) indicators was considered. Results: Sexual self-silencing had significant impacts across outcomes, gender, and countries. Furthermore, contrary to what might be expected, we observed no differences in self-silencing between the two countries; and in both countries, men were more self-silenced than women. Conclusion: Findings suggest that sexual self-silencing can compromise relationship quality and psychological well-being in later life. Health and clinical practice toward older individuals and couples should thus probe about and aim to improve the expression of sexual desires and needs.

  The paper sets out to study Norwegians’ experiences of non-monogamy. Data were collected by questionnaires in a web-sample of 4160 Norwegians (18–89 years). 26.3% of men and 17.8% of women reported that they ever had non-consensual non-monogamy. Consensual non-monogamy was reported by 3%. Compared to participants with no or non-consensual experience, consensual non-monogamy was highly related to relationship intimacy and positive sexual attitudes toward sex and sexuality. At the most recent extradyadic event, 21.5% of heterosexual men and 47.1% of gay/bisexual men reported condom use, which implies a risk for sexually transmitted diseases.

Journal of Sex Research.  ISSN 0022-4499. . doi: 10.1080/00224499.2020.1809615 Show summary

  Even though sexual activity frequently takes place with another person, research rarely focuses on how partners influence each other’s sexual lives. This study used the sexual dyad to compare the concept of actual versus perceived discrepancy in sexual interest and explored how each is related to older partnered individuals’ sexual satisfaction. Further, the study assessed the robustness of the association between sexual interest discrepancy and sexual satisfaction, if any, by controlling for emotional intimacy. The actor–partner interdependence model (APIM) using structural equation modeling (SEM) was applied to examine 677 heterosexual couples ages 60 to 75 in Norway, Denmark, Belgium, and Portugal. Although a couple’s actual discrepancy in sexual interest was not predictive of female and male partners’ sexual satisfaction, perceived discrepancy was negatively associated with sexual satisfaction in both partners after controlling for emotional intimacy. This indicates that the subjective feelings of being sexually dissimilar seem to be more important to sexual satisfaction than the actual mismatch among partners in older heterosexual couples. Moreover, the finding that emotional intimacy is linked with sexual satisfaction underscores the importance of a broader perspective on sexuality among older adults.

  What is the prevalence of using lubricants and medication to enhance erectile function among older adults, and what predicts such use? Survey data were collected in probability samples among 60–75 year-olds in Norway, Denmark, Belgium, and Portugal. In men, use of medication was highest in Norway (26%) and lowest in Portugal (12%). In women, use of lubricants was highest in Norway (31%), and lowest in Belgium (3%). Compared to those who had no sexual difficulties, use of medication/lubricants were higher in individuals with sexual difficulties. The findings contribute to an increased attention to the sexual health of older adults.

  Research on sex in later life has been concerned with documenting that older people continue to have sex and establishing the links between good health and sexual activity. Although sexual avoidance is common in clinical and nonclinical populations of older adults, little attention has been given to the motives for sexual avoidance. To address gaps in the literature on sexual avoidance, the present study explored the selfreported reasons for, and correlates of, sexual avoidance in older partnered individuals with probability samples of 60–75-year-olds in four European countries (Norway, Denmark, Belgium, and Portugal). Results revealed significant differences between men and women in sexual avoidance, with women reporting more avoidance than men. The main reasons reported for avoiding sex were sexual difficulties, health problems, partner’s sexual difficulties, and lack of sexual interest. Among men, significant predictors of sexual avoidance were age, relationship intimacy (the only relational predictor), physical health, and own and partner’s sexual problems. In women, significant predictors of sexual avoidance were age, relationship duration, relationship satisfaction, relationship intimacy, physical and mental health, and own and partner’s sexual problems. Thus, in men, health-related factors were more important predictors of sexual avoidance than relationship factors. In women, relationship factors were as important as health-related factors. These findings provide insight into an under-researched area. They also have important implications for healthcare and could inform the development of tailored sexual health interventions in older adults.

  OBJECTIVE: The potential impact of epilepsy on sexual function is important for patient welfare, but often neglected. This study explored the occurrences of different sexual problems in patients with both well-controlled and mostly refractory epilepsy, and compared these with equivalent information from the general population. METHODS: Between 2015 and 2017, a total of 221 adult inpatients and outpatients, mostly with intractable epilepsy, at the National Centre for Epilepsy in Norway, and 78 outpatients with well-controlled epilepsy at Lillehammer hospital participated in a questionnaire survey on sexual function. Information on the individual patient's epilepsy was collected. The results were compared with equivalent data on sexual function from 1671 adult Norwegians in the general population. RESULTS: Patients with epilepsy reported a significantly higher frequency of problems with orgasm, dyspareunia, erectile dysfunction, and feelings of sexual deviance. However, reduced sexual desire, premature ejaculation/climax, and vaginal dryness occurred at similar frequencies in the general population. After controlling for gender, we found no significant association between sexual problems and seizure control or use of enzyme-inducing antiepileptic drugs. In both genders, feelings of sexual deviance were associated with lower quality of life. Fewer patients with epilepsy were satisfied with their sex lives. The perception of sex as an important part of daily life was similar among women with epilepsy and women from the general population, whereas significantly fewer men with epilepsy than men in the general population reported that sex was an important part of their daily lives. Women with mostly refractory epilepsy reported asking for help with their sexual problems significantly more often than women in the other groups. SIGNIFICANCE: Some sexual problems occur significantly more often in patients with epilepsy than in the general population and feelings of sexual deviancy occur more frequently. No epilepsy-related factors could be identified as specific predictors. © 2019 The Authors. Epilepsia published by Wiley Periodicals, Inc. on behalf of International League Against Epilepsy.

  There is evidence that emotional connectedness can buffer the distress associated with sexual difficulties. Considering that older adults are at an increased risk of chronic illness, many of which (including their medical treatment) can impact their sexual well-being, this relationship may be particularly relevant for older couples. To start bridging the gap in the understanding of links between older couples’ emotional intimacy, distress about sexual function, and seeking professional help for sexuality-related issues, the current study used a 4-country sample with 218 Norwegian, 207 Danish, 135 Belgian, and 117 Portuguese couples aged 60-75 years. Two hypotheses were explored with a hybrid dyadic analysis: (1) Couple’s emotional intimacy is negatively related to partners’ distress about sexual function, but (2) positively associated with their help-seeking for sexual health issues. Less than 10% of participants in the current study reported seeking professional help, with the majority reporting their primary care physician as the contacted person. Emotional intimacy was consistently (and negatively) associated with female partner’s distress about sexual function across countries, but was unrelated to help-seeking for sexual problems. Understanding the link between a couple’s emotional resources and sexual distress can help health professionals, educators, and therapists to tailor effectively their work with older partnered adults who experience sexual health difficulties.

  The aim of the study was to explore attitudes towards sexuality and sexual behavior in older adults in Norway, Denmark, Belgium, and Portugal. A cross-sectional survey with representative samples of the population aged 60–75 years recruited through phone registers in Norway (676 men and 594 women), Denmark (530 men and 515 women), Belgium (318 men and 672 women), and Portugal (236 men and 273 women) was conducted. The data collection was carried out using an anonymous postal questionnaire. Four dimensions of attitudes towards sexuality were identified: ‘sex for love’, ‘sexual pressure in society’, ‘sex for well-being’, and ‘sexual changes and ageing’. Discriminant analyses identified three discriminant attitude functions: sex for well-being, sexual changes due to ageing, and sex for love. Portuguese men had positive attitudes towards sex as good for well-being in older adults but believed ageing was an obstacle to being sexual at this stage of life. Portuguese women believed sex was good for well-being and did not consider ageing an obstacle to sexual enjoyment. Norwegian men and Danish women believed changes in sexuality due to ageing were no obstacle to being sexual but did not believe that sex was good for well-being. The attitudes of Belgian and Danish men were largely inclined in the direction that sex is not particularly important for elderly people and that changes in sexuality occur due to the ageing process. Men and women were committed to the attitude of sex for love, although this was observed most in Belgian participants and least in Danish men. Positive attitudes towards sex for wellbeing and towards ageing and sexual changes correlated with less change in sexual interest and sexual enjoyment, and with increased frequency of intercourse and masturbation. To tailor successful sexual health interventions, attitudes of sexuality in older people should be addressed.

  Since HIV’s arrival, it has been stigmatised which has resulted in severe consequences for those living with HIV. Surveys on individuals living with HIV suggest that this group’s physical health and lives has improved through medical advancements but that stigmatisation remains an issue. There is little Norwegian research on the experience of HIV-related stigma among gay men, a group proportionally at greater risk of infection. The aim of this qualitative study was to investigate how HIV-related stigma is experienced and perceived by gay men living with HIV and how they deal with it. The study was conducted by interviewing 10 gay men living with HIV in Norway. The interviews were analysed through thematic analysis. Based on the narratives, the findings were organised into four themes and discussed as followed: ‘Encountered stigmatisation’, ‘Living with a secret stigma and the matter of disclosure’, ‘Self-Perception and self-stigma’, and ‘A sense of responsibility’. Contexts, connections, and implications of the findings are presented and discussed. HIV-related stigma is still experienced as an issue among some, but not all, gay men living with HIV. Self-stigma is reported as being the most prevalent issue. Suggested applications of the findings are presented.

  Aim: To investigate factors that predict partnered sexual activity in men and women aged 60–75 years from Norway, Denmark, Belgium, and Portugal. Methods: Cross-sectional study including national representative samples of people aged 60–75 years from Norway (676 men, 594 women), Denmark (530 men, 515 women), Belgium (318 men, 672 women), and Portugal (236 men, 273 women). Data were collected by means of anonymous questionnaires. Results: Generally, across countries, the two most important predictors of partnered sexual activity were positive attitudes toward ‘Sex for well-being’, and sexual problems in the partner. Other important predictors of partnered sexual activity included positive attitudes toward sexual changes due to aging, previous sexual activity, and relationship happiness. Conclusion: The sexual function of the partner and people’s own sexual attitudes were highly predictive of partnered sexual activity.

  The aim of the current study was to explore whether developmental trajectories of body satisfaction from adolescence to young adulthood predicted measures of sexual satisfaction in young adulthood, even when controlling for important covariates such as gender, weight development, relationship status, mental health, and frequency of sexual intercourse and masturbation. Data were collected from a population-based prospective cohort of Norwegian adolescents (n = 2,587) over a period of 13 years in four waves (1992, 1994, 1999, and 2005; mean age = 14.9 in 1992, 57.3% women). Latent growth curves were estimated for body satisfaction and Body Mass Index (BMI). Men reported higher sexual satisfaction, sexual activity, baseline body satisfaction, and BMI than women. The developmental trajectories revealed a slight increase in body satisfaction and BMI from adolescence to young adulthood in both genders. Moreover, structural equation models showed that baseline body satisfaction in both genders predicted sexual satisfaction as a young adult, independent of relationship status and frequency of sexual activity. Neither the development of BMI nor of body satisfaction predicted sexual satisfaction. The results elucidate the vital role of body satisfaction in sexual satisfaction in adults and the importance of addressing body dissatisfaction in childhood.

  What is the prevalence of using the Internet for love and sexual activities among older adults across Europe, and what predicts such use? Data were collected in probability samples among populations aged 60–75 years in Norway (N = 1271), Denmark (N = 1045), Belgium (N = 991), and Portugal (N = 509) using postal questionnaires. A total of 36% of men and 15% of women reported having used the Internet for sex and love purposes, most often to watch pornography. The use of the Internet for various love and sex purposes was higher in participants who had a partner, who had masturbation activity and who were satisfied with their current level of sexual activity. Multivariate logistic regression analyses showed that use of the Internet to find committed partners, watch pornography, buy sex products or seek information or advice was lower in Portuguese men than men in Norway, Denmark, and Belgium. Tailored websites to promote both sexuality and how to preserve a committed relationship are likely to prove important for the aging population.

  Abstract Objective: To study the relationship between age, gender, body mass index (BMI), body image, and perceived intimacy with partner and sexual satisfaction in young Norwegian adults. Methods: A questionnaire survey was completed online by 27.2 % (n = 568) of a representative national web sample of 2,090 persons aged 18–29 years. Results: Women were more dissatisfied with their body than men and BMI increased with age. A negative body image correlated with BMI, particularly among women. There was no gender difference in reported sexual satisfaction and perceived intimacy with partner. The most important direct path leading to increased sexual satisfaction was from perceived intimacy with partner, followed by body image and age. By influencing body image, BMI and gender influenced sexual satisfaction indirectly. Being male increased the likelihood of having a positive body image, which in turn increased the likelihood of reporting being sexually satisfied. Additionally, a lower BMI increased the likelihood of being satisfied with one’s body, which in turn increased sexual satisfaction. Conclusion: Body image is clearly related to sexual satisfaction, particularly in women. However, body image is not associated with the perception of intimacy with one’s partner, which is the most important factor for feeling sexually satisfied.

  This study estimates sexual debut ages in young heterosexual, lesbian, gay, and bisexual men and women in Norway. A questionnaire survey was completed online by 27.2 % of a representative national web sample of 2,090 persons aged 18–29 years. Three self-selected samples of 924 respondents completed an extended version of the survey online. Lesbian and bisexual women reported earlier experience of orgasm through masturbation than heterosexual women (median 13.1 versus 15.2 years), and heterosexual men (median 13.5) reported earlier debut than heterosexual women. There was a statistically significant difference between heterosexual and lesbian and bisexual women’s age at the first experience of receptive vaginal sex (median 16.8 versus 15.4 years). As regards experience of insertive vaginal sex, a significantly higher percentage of heterosexual men than women, and of heterosexual and lesbian and bisexual women, reported experience. It was more common among lesbian and bisexual women than heterosexual women to have had oral sex with another woman, but in neither group did the cumulative percent reach 50% by the age of 29 years and the median could not be estimated. Gay and bisexual men reported earlier receptive anal sex debut than heterosexual men. With regard to insertive anal sex, gay and bisexual men accumulated experience earlier than heterosexual men, and lesbian and bisexual women acquired this experience earlier than heterosexual women. Compared to heterosexuals, LGB persons of both genders engage in more varied sexual activities. Lesbian and gay persons have same-sex experiences at an earlier age than bisexuals.

  The aim of the study was to describe the sexual scripts related to ‘swinging’ in Norwegians with particular emphasis on issues related to STI prevention. We conducted qualitative in-depth interviews with 6 men and 6 women, including 5 heterosexual couples, 1 married man, and 1 single woman, all recruited from Internet groups for swingers. The results showed that the positive outcomes of swinging included the opportunity for participants to explore their own sexuality, see their partner have sex with others, and enhance their self-esteem. Swinging allowed them to act on secret fantasies and intrapsychic scripts. Negative attitudes towards male homosexuality, fear of sexually transmitted infections (STIs), and fear of being exposed were reported as problematic consequences of the lifestyle. Furthermore, the swinger script was more clearly defined for clubs than for private settings. In private settings, the swinger script typically borrowed elements from available scripts outside the swingers subculture, such as friendship or dating scripts. The lack of rules to protect oneself from STIs among the older swingers, and among swingers in private settings, may represent a potential threat to sexual health.

  This study examined the associations among the frequency of viewing Internet pornography, beliefs about how realistically pornography portrays sex, self-perceived effects of one’s pornography use, genital appearance satisfaction, and sexual self-esteem in young adults. Online data were collected from four convenience samples of university students from Norway and Sweden, members of a queer youth organization, and readers of an erotic magazine. Because of cultural similarities and the comparable magnitude and patterns of the bivariate correlations among the samples on the study variables, they were pooled into a single sample (N = 1,274). The majority of men (81.1%) and a minority of women (18.1%) reported at least weekly use of Internet pornography on their personal computers, whereas using a mobile phone or tablet was less common. Most of the participants had sought mainstream pornographic content. Those with a stronger belief in pornographic realism were more likely to perceive the effect of pornography use positively. A hypothesized relationship between self-perceived positive effects of pornography use and a higher level of sexual self-esteem was found for men but not for women. This result was partially due to higher satisfaction with genital appearance among the men who mainly watched mainstream pornography. Genital appearance satisfaction was linked to higher sexual self-esteem for women, but it was not related to the self-perceived effect of pornography use. The results indicate that pornography may expand personal sexual scripts for both men and women, and may have a positive, although modest, influence on the sexual self-esteem of young male adults.

  This study sought to study consumption patterns of gay-oriented sexually explicit media (SEM) by men who have sex with men (MSM); and to investigate a hypothesized relationship between gay SEM consumption and HIV risk behavior. Participants were 1391 MSM living in the US recruited online to complete a SEM consumption and sexual risk survey. Almost all (98.5%) reported some gay SEM exposure over the last 90 days. While 41% reported a preference to watch actors perform anal sex without condoms (termed “bareback SEM”), 17% preferred to actors perform anal sex with condoms (termed “safer sex SEM”) and 42% reported no preference. Overall SEM consumption was not associated with HIV risk; however participants who watched more bareback SEM reported significantly greater odds of engaging in risk behavior. The results suggest that a preference for bareback SEM is associated with engaging in risk behavior. More research to understand how MSM develop and maintain preferences in viewing SEM, and to identify new ways to use SEM in HIV prevention, is recommended.

  In contrast to the body of research focusing on female sexual desire, there has been very little research into patterns of male sexual desire. This study addresses this deficiency in the literature by providing empirical answers to the following questions: (1) is there a pattern of responsive sexual desire—defined as being predominantly receptive to a partner’s initiation of sexual activity without initially desiring it—among men? (2) Is this pattern associated with lower levels of sexual health than a more spontaneous pattern of male desire?, and (3) Are existing clinical observations regarding possible causes of reduced interest in partnered sex useful for understanding the more responsive men’s sexual desire? A large online survey about men’s sexual interest was conducted in 2011 among 2,215 Norwegian and Portuguese men aged 18–75 years (the average age in the sample was 36.5 years). Sociodemographic, health-related, sociosexual, and relationship-related information was collected. Three distinct patterns of male sexual desire were observed: decreased (23.6%), responsive (2.5%), and spontaneous (73.9%) desire patterns. Men in the more responsive and spontaneous desire groups significantly differed from participants in the decreased desire group, as they reported significantly higher levels of sexual interest, sexual satisfaction, and frequency of sexual intercourse and were less likely to have experienced sexual health difficulties in the past 12 months. Interestingly, participants with more responsive and spontaneous desire patterns were indistinguishable in terms of a number of sociodemographic, health-related, sociosexual, and relationship-related variables. The sole predictor of the responsive sexual desire pattern was proneness to relationship-related sexual boredom. Clinical observations about the roles of negative emotions, relationship strain, and specific sexual arousal patterns (homoerotic, autoerotic and/or paraphilic) in the etiology of hypoactive sexual desire did not seem relevant for men with responsive desire.

  Introduction: Clinical literature has suggested a link between job-related stress and sexual difficulties in men. However, epidemiological evidence for the association is largely lacking and little is known about the factors that may mediate or moderate the impact of workplace strain on sexual health. Aim: To assess association between job-related difficulties and men’s sexual health and address the mediating and moderating mechanisms behind the relationship. Method: Analyses were carried out using data from an online study carried out in 2011 on convenience samples of Portuguese, Croatian, and Norwegian men (n = 2,112). Multivariate logistic regression and mediation analysis were used to test the hypothesized associations. Main Outcome Measures: Job-related difficulties were measured by ten yes/no questions which addressed a range of adverse workplace situations. The experience of sexual difficulties in the past 12 months was assessed by seven dichotomous indicators developed in the NATSAL 2000 study. Results: Participants with job-related concerns reported lower sexual satisfaction than men without such concerns (F = 7.53, P < .001). Multivariate analysis confirmed the association between job-related and sexual health concerns. The odds of experiencing one or more sexual health difficulties in the past 12 months were about 1.8 times higher among men who reported highest levels of workplace difficulties than among participants who experienced no such difficulties. In addition to country-specific effects on sexual health disturbances (AOR = 1.98-2.22, P < .001), higher income (AOR = .87, P < .01), emotional intimacy with one’s partner (AOR = .93, P < .001), and having children (AOR = .62-.66, P < .01) significantly reduced the odds of reporting sexual health disturbances. In all three countries, the relationship between job-related and sexual health difficulties was mediated by negative mood (anxiety and depression), but no evidence was found for moderating role of emotional support (intimacy and fatherhood). The findings are discussed in the context of a multi-dimensional understanding of men’s sexual health.

  The purpose of this paper is to describe the prevalence of self-reported types of extradyadic romantic and sexual activity among adult Norwegians and to explore the role of infidelity in breaking up a permanent relationship. The results are based on 1,001 web interviews with persons ranging in age from 18 to 67 years. The majority of respondents reported having engaged in some kind of extradyadic romantic and/or sexual activity. Forty-five percent of the women and 39% of the men claimed they had experienced a previous breakup from a marriage or cohabiting relationship. Among those aged 50 years or older, the most important reasons for breaking up a previous relationship were infidelity (38%) and lost love (38%). More men (44%) than women (33%) reported infidelity. Respondents younger than 50 years were more motivated by boredom. Among respondents below the age of 50 years, the most frequently reported reasons for considering termination of a present relationship were quarreling (37%), poor sex life (29%), and “other” reasons (25%). Accordingly, infidelity was not identified as an essential factor for considering a breakup from the present relationship.

  ‘Friends with benefits’ (FWB) is defined as friends having sexual relations without commitment or romantic feeling towards each other. The purpose of this study was to explore the FWB phenomenon among young adults from a Norwegian, heterosexual perspective. Using the underlying theory of sexual scripts, and phenomenology as a research method, semi-structural interviews were conducted with twelve heterosexual women, aged 21 to 28 years, with experience in FWB relationships. Various elements of the relationship were explored: motives and function, definition of an FWB relationship, emotions, intimacy, and social influences. Results revealed that the main function of the FWB relationship appears to be the fulfilment of physical need in a safe context. Furthermore, the majority of subjects did not explicitly define the relationship, or have explicit rules to regulate it. Three types of FWB relationships emerged: the good friends, the lovers, and those who are on the hook. The study showed that people in FWB relationships ‘borrow’ elements from friendship scripts and love scripts, and combine them to form an FWB script. In the public sphere, behaviour is guided solely by this friendship script. It is only in the private sphere that the love script is present in addition to the friendship script.

  Objective: To analyze partnered and non-partnered sexual activity and sexual satisfaction in older adults from Norway, Denmark, Belgium and Portugal. Design and method: A cross-sectional survey, with probability samples of the population aged 60-75 years recruited by phone registers in Norway (676 men, 594 women), Denmark (530 men, 515 women), Belgium ( 318 men, 672 women), and Portugal (236 men, 273 women). Data were collected using postal, anonymous questionnaires. Results: In men, the percentage of sexually active participants (reported having had sexual intercourse, masturbation, petting or fondling) in the past year ranged from 83% in Portugal to 91% in Norway. In women, the percentage of sexually active during the last year ranged from 61% in Belgium to 78% in Denmark. Regarding frequency of sexual intercourse activity during the past month, men in Norway, Denmark, and Belgium (23-24%) most often reported 2-3 times per month, whereas most men in Portugal (29%) reported 1-3 times per week. Reporting masturbation activity was most common among Norwegian men (65%) and women (40%). Regarding sexual satisfaction, 40% - 60% of participants reported that they were sexually satisfied. Having a partner was the most important positive predictor of sexual activity and sexual satisfaction in all subgroups except Portuguese men.
