Most men feel a sense of revulsion in the idea of a homosexual act. It is why they have often reacted violently to even the slightest move on the part of a gay guy.
In the bad old days of my youth in NYC, it was common to see gay friends and gay co-workers showing up with black eyes and cut lips. We all knew what had happened the night before!
<><> The homosexual is till in the adolescent stage---w/ its discovery of sex/ genitalia.
<><> For the jaded male, Homosexual sex is considered far better than male/female type....thus it becomes a choice.

This leaves them vulnerable to various acts of street crime, perpetrated frequently by the sort of sketchy, desperate people most likely to be thought to want to take part in such things and be found in the bad parts of town.
But easier to blame it on those evil straights.
