hmmm
I don't think it would be a decision
maybe... things can happen, that could influence a person's loveuality. the whole nature vs nurture thing
but I don't think it's possible to actually make the decision to be gay or straight (or anything in between for that matter) yourself
I think it's more a case of just coming to the realisation that you're gay, or a particular loveuality.
Life experience definitely comes into that, as you'd have to have been in the circumstance where it becomes apparent. That would be the moment you find yourself attracted to something new.
I would consider it a little bit like viewing art. If I see a particular piece of art I don't in that moment choose to like or dislike it.
It might be I like art of a certain style (which would be brown townogous to a loveuality or special interest), but just because I find, say, cubism or modernism to be nice, it doesn't mean I chose to like it. And I couldn't fathom a way I could make myself not like it. Perhaps I could deter myself from looking at it, but I don't think that would make me like that art any less.
Once you've realised you like it you're stuck with liking it.
