Im and American teenager, and all the people who i've heard that they've had sex or something, they all had two things in common most of the time. One, they were both not too bright normally, and two, the girls that did it dressed with less than an appropriate amount of clothing... It's kind of hard to resist when you see a lot of girls going around wearing skirts that go down 2 inches and what not. Don't blame the teenagers, blame the fashion style.
