I don't think homosexuality is a choice. Society forces you to think it's a choice but in fact it's in one's nature. The choice is whether one expresses one's nature truthfully or spends the rest of one's life lying about it.
I've told people who have just started to make a film that the one thing you might experience is this feeling that everybody is conspiring against you because you're not necessarily able to tell what's real and what's not.
