Not bad, actually about to jump in the bath.
When educating children regarding sex, there are various techniques.
1. Teach them that sex is fine, here are some condoms, go have sex - enjoy yourselves. (hyperbole I know, but I'm keeping it short)
2. Teach them that sex is a Big Thing that should be avoided unless married. Having sex before marriage makes you dirty, condoms are not very effective, in fact, did I mention condoms? Forget I said that, just don't have sex till your married and everyone will be fine.
3. Teach them that the best way to avoid pregnancy and STDs is to avoid having sex. If they are going to have sex anyway, they should be careful and take suitable measures to protect themselves. Condoms et al.
They felt obligated to have sex just because it was now a normal thing to do, even though they weren't really feeling ready for it.
This is not abstincene though. This is about being taught how to handle peer pressure. If anyone feels obligated to have sex with somebody, something has gone horribly wrong. Indeed, I consider it as near rape as is possible. I had a girlfriend once who said she felt the same way, that she felt obligated to engage in sexual activities because I was a man. I dumped her shortly afterwards.
So sure, abstinence is good. No questions there. However, because we know that we cannot force, or pressure teens into NOT having sex (Abstinence only teaching does not work), we have to teach them about contraception as well. And that's the central debate really, should we ONLY teach teenagers abstinence, or should we provide them with all the weapons and defences they might need to keep safe.
Pro-abstinence (abstinence is one of those words that sound silly very quickly when you say it often) supporters would have us believe that teaching kids about condoms is passively encouraging them to go out and shag.
