Why would someone who has no desire to have sex with people of the same sex as him/her choose to have a million and one, or even more than one, gay experiences? Probably because they're not straight. No one is going to bang other dudes more than once if they have zero desire to do so. If someone says he/she isn't gay after having a million and one gay experiences, he/she is probably in denial as far as what his/her sexual orientation really is.
And I already said doing it once out of curiosity wouldn't make you gay. But if you didn't like it, you wouldn't do it a second or third or fourth time. Again, the desire to do so is there and it goes beyond just curiosity.
I never once implied that sexual orientation was a choice...Only that the sexual orientation of people who choose to have numerous homosexual experiences is, more often than not, homosexual (Or at least bisexual).
Also, I was kinda trying to tie this into Corbenk's original post, but fucked that up royally. All I'm saying is that there's nothing wrong with calling a spade a spade. If I frame houses there's nothing wrong with calling myself a framer. If someone sucks wangs there's nothing wrong with him calling himself gay. Not that it even should fucking matter what sexual orientation someone labels themselves as in the first place, but eh.
