Othering discourse and stigma amidst the identity formation process among gays, bisexuals and other men who have sex with men on HIV pre-exposure prophylaxis (PrEP).

With the global emergence of the HIV pre-exposure prophylaxis (PrEP), questions have emerged on which ways the social identity formation process among gays, bisexuals and other men who have sex with men on PrEP arise and constitute beyond exclusive sexual orientation expressions. We conducted a content analysis with thematic categories in a PrEP online group guided by group-web affiliation and individualization approaches. Individuals identify themselves as PrEPsters as part of a PrEP club, while dealing with conflicts on serosorting sexual partners and stigmatizing reactions towards people living with HIV/AIDS (PLWH). Self-worth and othering discourses towards PLWH emerged as complex themes in men's production of identity processes across four overlapping domains: (1) self-worth as a strategy to challenge individual HIV-acquisition-related anxiety and fear, (2) group-worth and group empowerment, (3) body control and reclaiming power on sexual health, and (4) othering discourses, HIV/AIDS stigma and criminalization of PLWH. Paradoxically, internal and external discourses to the group constitute and challenge identity differentiation; individuals on PrEP claim to fight against the HIV/AIDS stigma, while this reverberates alongst HIV-related discriminatory expressions in their discourses.
