I haven't read the article, but I highly doubt abstinace only education efforts are responcible, and bet it has more to do with generations, as the teens these days are children of the first wave of the children of the first generation since the sex lib movement.

My theroy is thus. The first generation told their kids one of two things, a. Screw everybody, or b. Don't screw ANYBODY, then the second gen proceded to screw away, got some emotional scars along with the AIDS crisis and such, thus told there kids, 'hey, this is what happens when you screw everybody, but, dude, sex is great when its great, so be careful and be safe'.
Well, that plus the text/twitter theroy, which is great.
