It may be stretching the point a bit, but part of the panel discussion focused on how the ravages of AIDS radically altered standards of beauty among gay men. Previous to the start of the epidemic, only a small percentage of gay men pursued the buff 'gym bunny' look, and it was a sort of fetishistic preference. As the epidemic began to ravage the community, it became more important for men to look healthy and HIV-negative, otherwise they could be rejected as a mate and maybe even face social ostracism. Nowadays, the gym bunny look is almost exclusively associated with gay men, to the extent that very muscular straight men can be mistaken for being gay.
