This is why I love living in Canada: we don't get 'abstinence only' propaganda. If we do, I've never seen it, and I live in a heavily religious community (2000 people, 6 churches).
What we were taught is that Abstinence is the only surefire way to avoid unwanted pregnancies and the transmitting of STD's, but it was always "But since I know you're going to experiment anyway, here's what you gotta do to play safe," There was never any scare tactics, condoms were and are freely available to anyone, and I remember there being teachers who would happily discuss things with you. Counselors who weren't judgemental pricks.
See, I'm a 'naturist' (I think that's the right term). I prefer to let nature take its course rather than doing all I can to limit natural behaviors and urges. Now I'm not saying we should be encouraging 12 year olds (or however old you may be when you hit puberty, I know people go from 8-13 typically) to be having sex, but since we know experimentation is going to happen, curiosity is a natural function and their bodies are being physically prepared for such things (including pumping them full of hormones that make them want it), the best thing to do is be realistic about it. Accept that, whether we try to keep them from it or not, if THEY want to do it, no amount of ignorant abstinence-only sex education in the world is gonna stop them from trying it.
The only way to get kids to not have sex is to let them decide for themselves that they don't want to. scaring them or flat out telling them not to only makes the curiosity stronger.
*insert obligatory inflammatory religion hate moniker here.* (Seriously, you people wonder why I hate conservatives and religion? this is one of the primary reasons: ignorance and power over knowledge and freedom)
