I dunno. Honestly, I wonder how much of it is really common knowledge, and how much is trumped up for ratings. I'm sure there are some teens out there up to this stuff, probably too many. But the media has a history of exaggerating this sort of thing.
Anybody remember Oprah and the whole 'rainbow parties' thing that had parents & school administrators ready to burn every jelly bracelet they could find?
Still, it's better than 'Secret Life of the American Teenager.' For some unknowable reason, Netflix suggested it to me. I watched the first episode. It was like someone set out to make a ridiculously cliched sex-ed video, and decided to carry on and make a soap opera out of it. Painfully bad!
