Well, when I was about six, I asked my mom for "The Real Truth About Sex and Santa Claus." Not that I thought they were in any way related...they were just the two big secrets of the time. Mom was very matter-of-fact about it, and I was satisfied with the answer. By about third grade or so, most everyone I knew knew about sex, generally not from their parents. Sex ed doesn't start around here until fifth grade or so. Unfortunately, it's mostly a basic "Sex will kill you" approach. Because they are under the illusion that saying "Sex will kill you" will prevent people from having sex, they don't get into actually educating people on how to protect themselves.
