I happen to share the experience with durasell here. Of the gay people that I know only one is a bit more promiscous, but he's under 20 so it's kinda to be expected (not that straight guys are any better at that age).
We constantly remind him to use protection ^_^. And if he didn't we'd kick his ass =).
I've known a lot of these guys for 20 years or more. As much as I'd like to believe they're leading the swinging lifestyle of their youth, it just strains the imagination at this stage of the game.
