PP again -- the Boy's Body Book, if you look at the comments on amazon, does not cover sex, intercourse, etc.

It was perfect for my son at age 9. It just deals with his body, how it is changing, etc. Doesn't much get into girls.

Yes -- this one is excellent

That's not really what OP was talking about. I believe she's looking for nonfiction books to help boys with feelings and transitions to adolescence and puberty.

All it took was googling "American girl books for boys"

I picked up the American Girl book about feelings for my daughter and think its great. Is there anything like that geared toward boys? Or kids in general? I just wondered why it was only directed at girls since boys have feelings too!
