Kids need sex education. Most adults that I know are woefully misinformed, and they just pass on their "knowledge" to another generation, if they talk to the kids about sex at all. I am a fitness instructor. I showed the women in one of my classes some anatomical drawings of the pelvic floor. These poor women had so little knowledge of even their own bodies, although all of them were mothers and grandmothers. The biggest revelation to them (from the pelvic floor diagram) was that women have 3 holes "down there." I felt a sadness for them. They were thankful for that little bit of education.
