Well, I have been meaning to ask around for a while.

My DS has grown incredibly over the past few months. He is truly a young adult now, with a behavior of a three year old sometimes, but that is another story :-)
I am looking for a book that I can just casually present to him, that will answer those sexual/body type questions from a boy perspective.
I do not have a problem talking to him about it, but he does. He does not ask me questions about it anymore, and I know that now with the hormonal surge and those HUGE changes in his physical appearance, he must have tons of them (questions, that is).

There seems to be tons of books for girls, my daughter likes especially the American Girl series, but nothing for older boys.
I am not loking for anything simplistic, I don't want DS to be offended :-)
