I think it’s a problem that in this discussion we’re seeing sex as something harmful and dangerous rather than something wonderful and rewarding on many levels—which it is when practiced safely. @eden2eve said, “They had plenty of very fulfilling activities, lots of sports, dancing and school activities, and they were very busy and happy,” but I’m pretty sure we all know that fulfilling activities neither render sex unnecessary nor curtail libido. Sex is not something most teens do because they’re bored or unhappy (some, admittedly)—sex is actually worthwhile on its own merits.
I don’t think the teen pregnancy argument holds (much) water. Abstinence—it has been shown—is not 100% effective at preventing pregnancy and being 18 doesn’t make a person any less likely to get pregnant. I do see @DrasticDreamer‘s point that if birth control isn’t available to teens, they shouldn’t be having sex because they’re not equipped to deal with the consequences, but I think the solution is to give them birth control. My high school distributed condoms and I think every high school should. The same logic applies for any argument revolving around STIs. The problem is not teens having sex—the problem is not being educated about how to do it safely and carefully. And once again, being over 18 doesn’t automatically endow you with the secrets of safe sex and it doesn’t make you less likely to contract an STI.
(And this is where my education argument takes off: Age of consent law combined with the influence of puritanical religion means that socially our education system has an excuse not to teach teenagers about sex. If they don’t learn about sex, they can’t learn to do it safely—knowledge which would dramatically reduce teen pregnancy if it were taught. Furthermore, after high school, you’re unlikely to go out an learn about sex on your own—firstly because there’s the crazy notion in society that sex is something you “just know how to do” and therefore shouldn’t have to ask about, and secondly because the topic is taboo to discuss—so there are a lot of uneducated adults in our society, having unsafe and unsatisfying sex because of the shitty sex education provided to them in high school. It’s not just about teens—it’s about being well-informed about sex as a society. But that’s all sort of a sidenote to the issue at hand.)
I agree that there’s some merit to the idea that children need to be protected from manipulative adults, but I think all of that should fall under sexual assault law, not age of consent. Adults sometimes often need to be protected from other manipulative adults as well.
And age is not an altogether reliable indicator of maturity. I have a friend who dated and lost her virginity to a 21 year-old when she was 17. She has no regrets about the experience and frankly she was much more mature than he was, so unlikely to be manipulated by him. Putting him in danger of prosecution would have been a travesty of justice.
Perhaps we’re worried about teens making mistakes and having sex with people they’ll regret later. This is a valid concern, but once again—not limited to teens—and I think not as dangerous as we think it is. Adults have sex they regret all the time. One mistaken night feels bad the morning after but (assuming all was practiced safely) isn’t a black mark on the rest of your life. Sex is a big deal, yes, but one night of bad sex won’t ruin a mature teen’s life. I would agree that some teens aren’t mature enough to deal with sex, but I would say that many are—and they deserve to be validated and educated. (I would also say I know many adults who are not mature enough to deal with sex responsibly, so the correlation there is fuzzy to me.)
I guess what my argument boils down to is this: many teens are already having and enjoying sex and sexual activities. The statistic I heard was just under 50% of teens were sexually active, but I imagine it’s higher if you take into account so-called “abstinent” teens who do everything other than penetration—activities which require just as much safety and education. If they have to be surreptitious about it and no one tells them how to do it right—then of course they’re going to make mistakes. If we validated that sex, we could also support them by providing them with health resources and educating them about potential problems so they could learn to avoid them and enjoy each other’s bodies happily and safely all the way into a happy and safe adulthood.
