Data from a cohort of gay men in Flanders, Belgium (1993, n = 553) are used in this analysis. It is assumed that, if prevention efforts were successful, younger gay men-sexually socialized during the AIDS era-should have more favourable perceptions of anal sex with a condom. This study reports on the practice and the pleasure and danger perceptions of protected and unprotected anal sex of young adult gay men (< or = 30) and older gay men (30+).
