Sex, is it really that hard to get over?

Billy Crystal once said that men and women can't be friends, because the sex part always gets in the way. That in the end men always want to have sex with women, even if the women is unattractive because the sex part is already out there and therefore the friendship is doomed. So what makes this statement different if it's two gay women, or two gay men? Why is that to the best of my knowledge and in my experience gay women and gay men usually are friends with mostly gay women or gay men, respectively? Do we not operate the same way as a man, or is it just that we constantly ignore that at least half of the friendship wants to bang the other half?

Personally, I know that there are quite a few of my friends that I find attractive and if I were single and they were single, I might this whole banging them idea a proper go, but because of circumstances they will never be more to me a friend, and of course the attractive friend that makes me look good when we go out. At the same time, lots of my friends (and I) have either hooked-up with each other or had relationships that didn't work out, and now are just good friends. How do we do that? I'm amazed by that. Even just now thinking about it, I remember conversations that I have been a part of where we compared notes about who in the room we had hooked up with, and by determining who had hooked up with more people in the room, who was the bigger slut. Straight men and women generally don't do that sort of thing, they see as if not impossible, uncomfortable. I'd also like to know about gay men. I'm not a gay man and I don't have many gay men friends, but do they screw around with their friends and then maintain these close friendships?

If this is a perk of being a gay woman I'll gladly take it, somehow we have worked out a way to not only get close to other gay women without the need for sex to be a part of it, but if sex were to become a part of it? We've found a way to either, 1) make it into a relationship that works because it was built on a friendship, 2) have a couple week fling, realize it's not going to work, and be able to laugh about it with everyone else later, or 3) have sex once and wake up the next morning not able to look at each other, but somewhere down the line go out for coffee and realize there is a friendship to be salvaged. And to those that let sex (not feelings, but sex) ruin a friendship, maybe you're straight after all.
