Yeah -
One of the hospitals here has a series of classes for young teens, on their bodies, sex, sexuality, the opposite sex - intended for teens to attend with their parents. I took my daughter to that class. We laughed so hard all the way home!
It is really difficult to get detailed and specific enough to be meaningful in a mixed class (gender, background, etc.) I made too many mistakes as a young man with relationships and sexuality because no one bothered to be down and dirty in discussions.
