“…It is possible some men who were in the group sex event were gay, bisexual and other MSM, which may result in sexual mixing between different risk populations. 36 Our study found that one in 20 (5.4%) heterosexual men and women had engaged in group sex in the past 3 months.

Background. Few studies investigate group sex among heterosexuals. The aim of this study was to provide an exploration of characteristics and practices among heterosexual men and women who engage in group sex. Method. We conducted a cross-sectional survey between May 2019 and March 2020 among heterosexual men and women attending a sexual health clinic in Melbourne, Australia. Participants were asked whether they had participated in group sex (sex involving more than two participants) in the past 3 months, the size of the most recent event, sexual activities in which they engaged, and condom use. Results. Of 3277 heterosexuals surveyed (1509 women and 1768 men), the mean age was 29.9 years (s.d. 8.8) and more than half (56.0%, n = 1834) were born outside Australia. One in 20 participants (5.4%) had engaged in group sex in the past 3 months with the number of events ranging 1-10 times. Kissing was the most common activity in group sex, and women were significantly more likely to kiss a same-sex partner than men. Overall, of 165 participants who engaged in vaginal sex, 57 (34.5%) reported always using condoms and changing condoms between consecutive partners. Of the 100 men and women who had condomless vaginal sex, 79 (79.0%) received or performed fellatio after condomless vaginal sex. Conclusion. About two-thirds of heterosexuals who engaged in group sex neither used condoms nor changed condoms between partners in the most recent group sex event. Safe sex messages on changing condoms between partners and between sexual activities should be reinforced for sexually transmitted infections prevention.

Background There are limited studies examining the early experiences of adolescent men who have sex with men (MSM), and the magnitude of changes in sexual practice among adolescent MSM is unclear. Therefore, we compared the sexual practice and trajectory among adolescent men who are MSM aged 16–20 years in two cohorts, 5 years apart in Melbourne, Australia. Methods A total of 200 self-identified same-sex attracted men aged 16–20 years were recruited in each of HYPER1 (2010–2012) and HYPER2 (2017–2018) using similar methodology. Men completed a questionnaire about their sexual practices. Men were also asked to report the age of first sex with different sexual activities with men and women. Results Compared to HYPER1, the median age at first sex with men was slightly increased in HYPER2: receiving oral sex (17.2 years in HYPER2 vs 16.5 years in HYPER1), performing oral sex (17.3 years vs 16.4 years), receptive anal sex (18 years vs 17.0 years) and insertive anal sex (18 years vs 17.3 years). Similar patterns were also observed in sexual practice with women: performing oral sex (17.0 years in HYPER2 vs 16.8 years in HYPER1), receiving oral sex (17.0 years vs 16.3 years) and vaginal sex (17.0 years vs 16.7 years). Conclusions In general, there was a small delay in first-sex activity among adolescent MSM between two cohorts 5 years apart. Most adolescent MSM started their sexual practices before the age of 18 years and have engaged in activities that are at risk of HIV and STI. Health education and promotion, including regular sexual health check-ups, are important for HIV and STI prevention and intervention in this population.

Background The patterns of sexually transmitted infections (STIs) in populations may be influenced by the sexual mixing within the population. We aimed to investigate the assortative sexual mixing pattern by bisexuality in male–male partnerships. Methods This was a retrospective repeated cross-sectional study of men with mostly regular male partners attending the Melbourne Sexual Health Centre between 2011 and 2019. Data on sexual practices, including their sexual practices, presence of other male/female sex partners and the gender of sexual partners in the previous 3 and 12 months, were collected using computer-assisted self-interview. We calculated the proportion of male partnerships where at least one man in the partnership reported a female sex partner. Results A total of 2056 male–male partnerships (i.e. 4112 individuals) with a median age of 29 years (IQR 25 to 35) were included. Overall, in 94.4% (1941/2056) of male–male partnerships both men had male partners only; however, in 5.5% (113/2056) of partnerships, one man had both male and female partners, and in 0.1% (2/2056) partnerships, both men had both male and female partners. No assortative relationship was found on the sexual mixing by bisexuality in male–male partnerships due to the low assortativity coefficient (r = 0.006, 95% CI: −0.004 to 0.016). Conclusion One in 20 male–male partnerships had at least one man who had both male and female partners within the preceding year. Individuals were not selective by bisexuality, suggesting that partnerships of bisexual individuals are mixed proportionately to the distribution of their characteristics. Still, these sexual mixing practices may affect STI transmission dynamics.
