So abstinence education doesn’t work — even Bristol Palin admitted that. Teenagers need realistic, accurate information about sex and pregnancy. It simply makes sense that teenagers get that kind of information as part of an overall biology/health education program in school, so that what is taught is both correct and consistent. The alternative is to have kids learn about sex on the playground or, even worse, from potential (hopeful?) lovers. That’s where ideas like “you can’t get pregnant the first time” and “if you love me, you’ll let me” come from. So, yes, sex education is a good thing. But should it really come from a talking cow?
