Perhaps you would need to consider (not talking about doing studies like you are, though) that these kids are often not "planning" on having sex and it just happens cause they get carried away after putting themselves into bad situations or flirting with the idea even though they know or think its wrong. I do know that UT has had one of the higher teen pregnancy rates at one time or another, and not sure why unless its the "jack" Mormon population. But then again, we have such high expectations we carry a lot of guilt around as a rule : ) UT's population is now outweighed by non-members anymore, too, so it may not be all members even. But the culture, still, is more wholesome. They have billboards for modest prom dresses, wedding dresses, etc. for instance. (You don't see that other places that I know of). Basically goes back to the adage "good girls get caught." Not always, and not all "good girls" but you get my point. My daughter just tried to skip but did it so blatantly dumb that I couldn't even give her an out if I'd wanted to. i chose to let her pay the consequences so she wouldn't keep doing it, but she's so honest she couldn't lie about it either and there were others who DID lie.... (It was Senior skip day but she'd also done it another time right before which is what got her caught).
