Perfect age. Biologically speaking, of course. It's only recently (the past few hundred years) in the "civilized" world that we raised the age of marriage/consent. Why do you think women go through puberty around that age?

EDIT: Okay, so apparently a lot of people got offended/angry/etc that I said this, and while I stand by my words, I would like to point out that I may have phrased some things badly. I don't think children should be having sex before ~16, nor do I think that as soon as reach their first moonblood, they are ready for sex. The idea of being "ready for sex" is such a complicated idea and there isn't one answer to it. It highly depends on the individual's physiological and psychological development, the situation, the other people involved, and many other factors. To be fair, I'm 22 and I'm very sexually inexperienced. I didn't intercourse until I was 20. I didn't even kiss someone until I was... sixteen, I think? I have friends that started having sex at fucking 14 (with people their own age... ish). It's such a grey area that I don't there is a definitive "children shouldn't start banging until X years of age".

P.S. Most of that is irrelevant to what the original idea of this comment was. That these girls who appear to be around 14 or so (my highly "educated" and "informed" guess) are visually attractive. I think most people who are into girls would agree. I don't think that this attraction should be acted upon by someone much older than them.

P.P.S. Also, this comment was a half-joke anyway. You shouldn't take half of the shit I say seriously, but I don't take life seriously. I joke constantly and my humor is very dry. I had a lot of fun arguing with everyone in this thread though, and while I'm sure a lot of people go pissed off, I was laughing the whole time. So long, and thanks for all the fish!
