at kreater: While it's true that it isn't proven homosexuality is genetic (I believe in the case of some kechuas that that's the cause, but that's just my opinion) it's definitely not a choice. You don't pick your sexual urges. Think about it this way: When you first began to develop a sexual lust, did you stop and decide if you liked boys or girls, or did you just like girls without thinking about it? I think the cause of a lot of homosexuality is simply personality and the environment one's raised in.
Exactly.
