I think the bad part about it is that television and other popular media isn’t allowed to give sex ed. What they end up doing is giving as much of a teaser as they can without giving away the plot – sort of a sex ad. The problem is that, if you haven’t seen the movie, you don’t get the in-joke. Feed kids TV, and they’ll end up saying, “Hey, that looks cool. We should have sex. …What is it, anyway?”
I think the most important thing is to teach kids about abstinence and condoms. That way you’re not telling them to go out and have sex but you’re saying that if they do they need to be protected.
