Apparently in the states only 47% of highschool students have had sex. Really, I guess that number isn't that low but it surely felt like a whole lot more than that when I was in highschool...the feeling that "everyone else" is doing it is obviously an illusion. Thinking back I was actually pretty early having sex, compared to friends, and I was well into grade 12...
