An (un)restricted living
People living with HIV, who have access to treatment, now have normal life expectancy. However, stigma and discrimination continue to affect health and well-being. We conducted focus groups with people living with HIV (n = 37), and key informant interviews (n = 20) with clinical and non-clinical workers who support people with HIV between May and November 2023. We aimed to explore the ongoing challenges and concerns faced by people living with HI…
Needs & networks
Our proposed categorisation may facilitate the development of differentiated person-centred HIVST programmes. HIVST implementers should carefully consider individuals' unmet testing needs and perceived levels of social support, and design context-specific HIVST strategies that link people lacking supportive social networks to comprehensive HIV care
Exploring practices to enhance benefits and reduce risks of chemsex among gay, bisexual, and other men who have sex with men
BACKGROUND: Chemsex is the intentional combining of specific drugs with sex, primarily by gay, bisexual, and other men who have sex with men (GBMSM), to enhance intimacy, pleasure, and prolong sexual sessions. Practices vary across geographic and social settings. Participants report benefits and risks of chemsex. Studies have previously reviewed chemsex practices and harm reduction interventions separately. This review aims to examine both togeth…
The Impact of First UK-Wide Lockdown (March–June 2020) on Sexual Behaviors in Men and Gender Diverse People Who Have Sex with Men During the Covid-19 Pandemic
The global COVID-19 pandemic resulted in strict social distancing measures restricting close physical contact. Men (cis and trans) and other gender diverse people who have sex with men (MGDSM) are at higher risk of sexually transmitted infections (STIs) and may have experienced changes in sexual behavior during government restrictions on social and sexual contact. We aimed to examine self-reported sexual behavior of MGDSM during the first UK-wide…
Hi-fun among men who have sex with men in Bangkok
The use of specific drugs (e.g. methamphetamine, GHB/GBL and other stimulants) to enhance sex among men who have sex with men (MSM), is the focus of global public health concern because of links to social harms, poor mental and sexual health. Often called ‘chemsex’ in Western settings or ‘ hi-fun ’ in Southeast Asia, this type of sexualised drug use is increasingly visible in Thailand where the unique sociocultural and legislative environments sh…
Mental Well-Being and Sexual Intimacy among Men and Gender Diverse People Who Have Sex with Men during the First UK Covid-19 Lockdown
This mixed-methods study aimed to explore mental well-being, circumstances and strategies around managing sexual intimacy and risk during the first UK COVID-19 lockdown (Spring 2020) among men and gender diverse people who have sex with men (MGDPSM), commencing while lockdown was in progress. n = 1429 MGDPSM completed the survey and 14 undertook an in-depth interview. Low mental well-being was reported by 49.6% of the survey participants. Low men…
Experiences of and attitudes towards HIV testing for Asian, Black and Latin American men who have sex with men (MSM) in the SELPHI (HIV Self‐Testing Public Health Intervention) randomized controlled t…
SELPHI was prospectively registered with the ISRCTN (ref: ISRCTN 20312003 )
Exploring Mechanisms of Action
SELPHI involves two interventions: (A) It provides one HIV self-testing (HIVST) kit; (B) It offers 3-monthly repeat HIVST kits if participants report ongoing risk. A logic model underpinned by the Behaviour Change Wheel informed the design of the intervention. SELPHI recruited 10,135 cis-men and trans people in England and Wales, all reporting anal sex with a man. This paper explores how the interventions were experienced and the pathways to impa…
Risk, reassurance and routine
HIVST following risk events will likely be limited to those for whom existing service provision is insufficient to meet immediate needs based on structural or personal barriers to testing. Obligations of biological citizenship are central to MSM's understanding of the utility of HIVST. Secondly, HIVST is useful in complying with social norms and meeting the perceived demands of biomedicine
What We Can't See? Understanding the Representations and Meanings of UAI, Barebacking, and Semen Exchange in Gay Male Pornography
Since the late 1990s, the use of condoms within gay male pornography has been on the wane. Moving from a niche category into more mainstream forms of commercial pornography, unprotected anal sex has become a dominant theme within this sphere of gay male sexual representation. However, while the definition of what constitutes bareback pornography may at first sight appear unproblematic, this article argues that meanings and understandings of unpro…
Porn laid bare
This article details the preliminary findings from Porn Laid Bare, a collaborative research project between the University of Sussex and the Terrence Higgins Trust, Brighton. We explore the multidimensional relationship that respondents identified as having formed with pornographic material, together with its role within gay male subculture. We then consider how interview respondents understood and conceptualised bareback pornography. Our finding…
