Guys are horny creatures. The only reason there aren't more promiscuous straight men is because there aren't as many opportunities with women. Women are all stuck up lolz.
The other side is that gay culture promotes this behavior, but the homosexual community gets all upset when people say, "Stop fucking and stop doing meth!" This is just because the gay community is too sensitive and won't take an introspective look at some of its more self destructive lifestyle habits, especially from us gay-hating, antagonistic breeders. My uncle, who's been out of the closet for years, gets pissed at his gay friends when they're offended when this problem is brought up.
But calling everyone homophobes doesn't make the problem go away.
