I really don't understand why teens need this without a parent (at least, I'm assuming that's without a parent). Saying that kids are going to have sex is just condoning it. In some states it's illegal for minors to have sex so, assuming that's the case, the pill would be grounds for arresting the girl who's buying it.
I, personally, don't understand the whole situation. I haven't had sex yet, and some of my friends are holding out (or at least, were the last time I talked to them about this), so the idea that people younger than me are dealing with this issue is just hard to conceive. When I was at that age I was worrying about keeping up with classes, getting into college, and figuring out what I wanted to do with my life. I really didn't have time to add sex in there. Plus I wasn't impressed by the guys around, but that's a different issue.
Some of the problem, I think, is the media like others have said, but also the fact that they are starting to put sex ed as a class in schools. I understand we have the technology to prevent pregnancy by taking a pill or using a condom, but why not explain to kids that the point of sex is to CREATE A KID. Most animals don't have sex for fun, they use it to reproduce. I think it's humans and dolphins that just do it for fun. I may be completely wrong, but if it was explained that sex is a means to produce a kid, which comes with some extra chemical benefits, instead of a magical experience that should only be done with someone you love and that may produce a baby, maybe kids would be more careful.
Maybe it was just the class I had, but the whole message I got was sex is a good thing; it makes you feel good and you can connect deeply with your partner, but there is the side effect of having a kid. So, if you want to avoid having the kid but enjoy the other part, just use a condom and the pill and you're all set. Okay, maybe that last part wasn't exactly phrased that way, but that's how it sounded to me. I mean, doesn't handing out condoms just give the impression that you want the kid to have sex. If someone gave you money, they'd expect you to use it at some point. How is this any different?
