"Do you think pedophilia is a sexuality that you dont have a choice about? (similar to not having a choice about homosexuality)"I'm going to give a very tentative and qualified "maybe" because I don't know enough about pedophilia (and since I'm pre-writing this while packing for my Florida vacation, I don't have time to look up more information). I really have no idea if pedophilia is something you have a choice about.
If I'm just totally speculating here (can I add anymore qualifiers?), I can see it being somewhat biological. For one thing, I don't think anyone would "choose" to have what's widely considered one of the most, if not the most deviant behavior. And because it's so frowned upon (understatement of the century), I don't know how easy it could be to learn the behavior. Maybe it is learned, but you can't help it once you've learned it. Maybe it's a chemical imbalance. Who knows - I certainly don't.
Certain types may even be instinctual. Young, healthy females are still physically attractive to men. Some girls can biologically mature at 12, 11, or 10 years of age. From an evolutionary perspective, they are "adults" and potential mates. In past cultures (and unfortunately some current ones), this was recognized by females getting married at these young ages.
However, biology does not dictate morality. Even if you could come up with a scientific explanation for why someone would like a 10 year old, or hell, why someone would like a toddler or infant, that does not make it ethically acceptable. It doesn't matter if it evolved or if there's a gene or if there's some sort of chemical imbalance. Pedophilia is still morally wrong because the younger party is not emotionally developed enough to consent.
That's why I'm always so annoyed when someone equates homosexuality with pedophilia (not saying the question-asker was, just saying). Homosexuality is between two consenting partners, while pedophilia is not. Even if they had similar biological causes, that doesn't mean they should be treated the same ethically.
I freely admit I know little about the previous research done on pedophilia. If someone would like to enlighten us in the comments, feel free to do so.
