For there to be a choice in this, you have to have two options. If you cannot get an erection from the idea of having sex with a man, you cannot have sex with them, so there is no choice.

Its a part of who you are. Arguments about choice in homosexuality are arguments that attempt to justify bigotry and the illusion that gay people could become straight anymore than I could have sex with another man even if I "chose to".

EDIT: Game, please don't mistake me for calling you bigotted. I just think you might be listening to a lot of rationales from those who are. Its my personal belief, and I think the logical one, that we can't expect gay people to change their sexuality any more than we could change ours. Sexuality is integral to who we are as people, much more so than music or movies or culture. To deny our selxuality is to deny ourselves.
