Gay men with diagnosed HIV can adopt a number of strategies to reduce the risk of transmitting HIV to others, although research has typically focussed on condom use. Interviews with 42 HIV-positive gay men who reported recent engagement in anal intercourse without condoms explored their awareness of sexual risk and their perceptions of non-condom-related strategies to reduce it. In articulating men's ambivalence for strategies that can only reduce the risk of transmission, rather than eliminating, the findings have implications for the consideration and integration of new biomedical interventions to reduce the likelihood of HIV transmission.
