Query: Terrific for your teenager

I bought this for my 15 year old son for reference and for his information.His father won't talk to him about sex and he is too embarrassed to talk with me. In fact, I had to leave it in his room and he swore he wouldn't look at it. That he had learned everything he needed to know in 1 week of sex ed at school (!)2 weeks later he thanked me for buying it. Still trying to keep the lines of communication open but at least now I know he is armed with knowledge.
