      Smartphone-based dating applications like Grindr are popular among men who have sex with men (MSM), and it is common for MSM to engage in sexual activity with other users. Despite this, there is limited research on MSM's negotiations of consent for online sexual interactions and in-person sexual encounters. This study examined MSM's understandings and practices of consent on dating apps and in person. Interpretative phenomenological analysis of 25 interviews with MSM dating app users revealed that many participants could identify key aspects of consent but did not always apply those understandings to their own practices. For online sexual interactions, some participants viewed consent as connecting to a dating app - a practice I term "clickable consent" - while other participants viewed consent as continuous and communicated consent in explicit and implicit ways. Although all participants negotiated consent online in preparation for an in-person sexual encounter, some renegotiated consent in person with explicit or non-explicit communication, while others did not renegotiate consent in person. Results shed light on how MSM's online conversations impact their in-app and in-person sexual activities, and reveal challenges that MSM face in digital and physical spaces. Conclusions, implications, and suggestions for future research are discussed further.

       Introduction: South Africa has the highest burden of HIV in the world with over 8 million people living with HIV. Young women and girls account for a quarter of new HIV infections while making up only 10% of the population. A key driver of HIV incidence is transactional and survival sex between adolescent girls or young women and older men (the latter referred to as 'sugar-daddies' or 'blessers'). This paper expands on the existing literature on age-disparate and intergenerational relationships to provide social and behavioural interpretations of how young men, commonly omitted from studies on this topic, and women in concurrent relationships with both their peers and older partners perceive and navigate sexual risk.
    Method: We conducted a qualitative study in a rural setting of uMgungundlovu District, KwaZulu-Natal Province, with purposively selected male and female participants aged 18-24 years old in age-disparate relationships. Semi-structured in-depth interviews (IDI) were conducted and analysed using interpretative phenomenological analysis (IPA) to explore existing information, motivations, and behavioural practices around relationships and sexual risk.
    Results: The themes and related sub-themes found through IPA included the following: (1) navigating dating: narratives that show a strong preference for being in an age-disparate relationship; the challenges that young people face when choosing an older person as a side partner; and social media applications seen as creating opportunities to meet side partners; and (2) the distribution of love and trust in a multi-party sexual network: condom (mis)use differentiates between straights-those in a serious relationship-and sides; and the power of eye-test seroguessing, the praxis of testing people visually for HIV in nullifying existing knowledge about sexual and reproductive health risk.
    Discussion: This research offers an understanding of how schemas of non-condom use are organised. We observed that while condom-less sex is often viewed as essential to building social capital in a serious relationship, it is not the only factor that determines sexual relationship power. Eye-test seroguessing not only develops consortium (trust, reciprocity, and solidarity), but it fulfils the psycho-social need to belong to a network of serious relationships. Moreover, it is critical to the enactment of masculinities because it consolidates femininity to keep men happy, i.e., by being passive in the sexual encounter, women constrain their self-efficacy to act contrary to the conventions of reputable women. Therefore, it is plausible that in the serosorting that occurs prior to unprotected sexual acts, the power of eye-test seroguessing limits the ability to engage in safe sexual practices.

      Adolescents who lack traits valued by peers are at risk for adjustment difficulties but the mechanisms responsible for deteriorating well-being have yet to be identified. The present study examines processes whereby low athleticism and low attractiveness give rise to adolescent adjustment difficulties. Participants were public middle school students (ages 10 to 13 years, Mage = 11.54, SDage = 1.00) in the USA and Lithuania (300 girls, 280 boys; 52.7% girls). Self-reports of alcohol misuse and loneliness were collected three times during an academic year (M = 12.3 week intervals). Athleticism, attractiveness, unpopularity, and peer rejection were assessed through peer nominations. Full longitudinal mediation analyses examined direct and indirect pathways from stigmatized traits (i.e., low athleticism, low attractiveness) to adjustment difficulties (i.e., alcohol misuse, loneliness) through two indices of low peer status: unpopularity and rejection. The results indicated that the possession of stigmatized traits predicted escalating unpopularity, which, in turn, predicted increasing adjustment difficulties. Similar indirect associations did not emerge with rejection as a mediator, underscoring the unique role of power and prominence (and the lack thereof) in socioemotional development. The findings underscore the adjustment risks and interpersonal challenges that confront children and adolescents who lack traits valued by peers.
