You have absolutely no proof of that other than your silly “intuition” I guess. Oh, and your irrefutable anecdotal evidence of Nathan the effeminate boy, of course if that were proof ALL effeminate boys grow up to be “gay” right? But then your “sometimes” it’s a choice claptrap comes into effect? I’m confused.
I gave you a link to what happens when androgen production is in imbalance. John O correctly pointed out that you can’t measure hormone levels of a corpse to determine if it were homosexual or not. Yet you hang on to the notion that homosexuality is induced by hormones OR chemicals? (What chemicals would those be?) And as usual, you perversion justificators usually have a “friend” who is gay and that’s enough to defend his honor with the usual proof “the earth is flat”.
BTW, we're all born heterosexual...paraphilic disorder is what changes that. To say some people are born with paraphilic disorder is to say some people are born attracted to animals. You've lost your mind.
