Do you make a concious to be straight? Nope. Ditto for gay, bi, a etc.
Did you feel different before realising you were straight? Nope. Ditto for gay, bi, a etc.
Did realising you like tits or penis suddenly change you in other ways? Nope. Ditto for gay, bi, a etc.
Gay is the same concept as straight. It works the same way, it just looks different. The difference is outside- how people treat you, how you're worried people will treat you etc. Inside it all works the same.
People can choose to pretend not to be straight or gay or to hide it, they can't choose how they actually feel though. It may also develop or change. That's still not a choice though. It's physical stuff causing mental stuff. You can't change that physical stuff by will power so you can't change the mental result.
