I was lucky enough as a teen to have a two different friends with detailed sex ed books. One friend's parents had "The Joy of Sex" and for a clueless teen it was great. It showed how to please a woman and gave many other great tips for being a good lover. Plus it's illustrated very well too.
My other friend's parents actually *gave* him a book on sex ed. I don't remember what the title was now. It was much older than "Joy" (1950's?) but it did include enough to get a good idea about what to do to stimulate a woman. It even made a point about how important clitoral stimulation is. The surprising thing, this friend is a Baptist. I guess his folks wanted to make sure he knew what to do on his wedding night.
If it wasn't for those two books I would have had to fumble my way to figuring out what to do to please a woman. I did get the condom lecture from mom and my two big sisters and I was using those before it was even cool. You had to ask for them from the drug store back then, they kept them behind the counter.
For kids today with the internet, it is so easy to find info, it's a whole different world. I've even learned a few new things I wouldn't have thought of on my own.
