Hormones trump abstinence way too often for it to be a realistic policy.
Finally someone that fuckin gets it! I mean Jesus have any of you clowns ever been 16, 17 or 18 before in your lifes? for most teenagers when they end up in a room with a horny female who wants to get it in, that abstinenance garbage gets thrown right out the window. The best thing is contraceptives so they won't get a disease or another teen pregnancy.
