Meh, by the age of 12, I was already jacking-off at least once a day. And I'm sure most girls have had their first period by then. At that point, I think it's safe to say that age is just a number.

A 12 year old dating someone twice her age isn't as big a deal as some might make it out to be. He's not even really old enough to be her dad, although I'm sure it's possible. Way back in the early days, you were married by 13 and had kids by 16. People didn't live very long back then, so you didn't have time to waste.

This situation might not be "socially acceptable", but who gives a shit about that? If she were 18 and he were 36, this wouldn't even be news.
