In a minority of gay men, sexual risk practice indicates strategic positioning for perceived risk reduction rather than unbridled sex.

The aim of this analysis was to examine gay men's sexual risk practice to determine patterns of risk management. Ten cross-sectional surveys of gay men were conducted six-monthly from February 1996 to August 2000 at Sydney gay community social, sex-on-premises and sexual health sites (average n = 827). Every February during this period, five identical surveys were conducted at the annual Gay and Lesbian Mardi Gras Fair Day (average n = 1178). Among the minority of men who had unprotected anal intercourse which involved ejaculation inside with a serodiscordant regular partner, there was a clear pattern of sexual positioning. Few regular couples were both receptive and insertive. Most HIV-positive men were receptive and most HIV-negative men were insertive. Among the minority of men who had unprotected anal intercourse which involved ejaculation inside with casual partners, there was also a pattern of sexual positioning. Whereas many casual couples were both receptive and insertive (especially those involving HIV-positive respondents), among the remainder HIV-positive men tended to be receptive and HIV-negative men tended to be insertive. These patterns of HIV-positive/receptive and HIV-negative/insertive suggest strategic risk reduction positionings rather than mere sexual preferences among a minority of gay men. If so, they point not to complacency but to an ever more complex domain of HIV prevention.
