The word "choice" is quite an unfortunate one to use in this debate - I don't exactly choose when I have a boner, neither do I choose to be attracted to a given person on a sexual level.That choice is made throughout a person's whole existence as far as self awareness go.
I would assume that you don't either, unless you're asexual. By the way, asexual people seem to be excluded from our little chit-chat, I wonder why.
Puberty doesn't just "hit" at a pre-set moment in your life - it's a gradual process. You don't immediately grow a bush of hairs on your intimate areas - some changes begin on the internal part of your body and mind.most kids know they are gay before puberty hits. i knew i was attracted to men long before that. it has nothing to do with hormones.
