This has been an interesting question for years. Recently in the United States, conservatives have been pushing a program of teaching students abstinence, and not teaching anything about the biology involved in reproduction. Studies in these schools have determined that these students are dreadfully unprepared for real life situations. They often have the misconception that such activities as kissing or hugging can cause pregnancy. They have no idea how std's are transmitted. No idea about aids and safe sex. I am not talking about 3rd graders. These are teenagers, all thru puberty and full of raging hormones.

The ideal situation would be parents educating their children at home, but so many parents are uptight about sex, and are unlikely to broach the subject.

I believe that schools must teach sex education with a format of teaching biology, and responsibility, These teens need to know that STD's can be passed through oral sex, straight sex, and how to protect themselves against disease. Sure, it is fine to mention that the safest route is abstaining, but if they are going to be active, they need to know how to prevent unwanted childen and disease.
