Sexual sensation seeking, reduced concern about HIV and sexual risk behaviour among gay men in primary relationships.

Gay and bisexual men who indicated they were currently in a primary relationship with another man (N = 230) completed measures of HIV treatment attitudes, sexual risk behaviour and sexual sensation seeking. Results indicate non-primary partner sexual activity is common in many gay relationships and men in non-exclusive relationships possessed greater levels of sexual sensation seeking and treatment-related reduced concern about the dangerousness of HIV than men in exclusive relationships. Results also suggest that individuals who were members of HIV-seroconcordant relationships were more likely to engage in unprotected sexual activity with their primary sexual partners than gay men who were members of HIV-discordant couples. A series of regression analyses revealed that reduced concern about HIV mediated the relationship between sexual sensation seeking and sexual risk behaviour. The next generation of HIV prevention interventions must address the attitudinal shifts that have occurred among some gay men regarding the seriousness of HIV and should be sensitive to the dynamics of gay relationships.
