I LOVE TCOYF and have made it available to my kids since I started reading it 7 or 8 years ago. They know all about how a woman's body works. I'd love one that factually but thoroughly explains a man's body.
However, I'd also like to find a book that might teach him more than just that. Like, what to expect from his emotions, the things he might experience and how to deal, etc.
Any book recommendations?
