I'm not going to argue the studies, because I think none of the studies have been good. So far, the most we've got is correlations. I still believe there is a non-social explanation to some homosexuality.

I've often found that there seems to be, among the stories of homosexuals and heterosexuals (who were experiencing) a common theme among males that "discovered" they were one way or the other. I call it: "The Dick-In-Mouth Test"

It seems to actually be pretty clear that in their own words, the subjects identified that they were going to try and fool around with a male partner they were comfortable with and there were two reactions:

One: the subject would see the other males dick, have a near insatiable desire to put it in their mouth, and think that this was a good idea.

Two: the subject would (by one way or another) have their friend's dick in their mouth, and immediately decide that this was a bad idea.

One is homosexual. Two is heterosexual.

Nobody seems to have the reaction of: "Meh, I could go either way with this dick in my mouth" or "I'm not sure what to think of this dick in my mouth, but I think I could be persuaded one way or the other, lets give it some time."

Nope, it seems to be pretty clear and pretty consistent in each case.

I tend to think that such a clear reaction for their first homosexual encounter is likely going to be an indicator of a genetic pressure rather than a social pressure.

You don't need to teach a straight guy to like boobs. You also don't need to teach a gay guy to eat dick.

Nature, uh, finds a way.
