I've had that problem with my own kid, who is 11. For the Oregonian, I recently reviewed (positively) The Boy Book, but I haven't offered it to her to read because in the beginning the 16 yo main character let a boy she just met kiss her and fondle her breasts. If kid wanted to read it, I wouldn't say no, but I haven't suggested it either. If kid were older, I think I would feel differently, but I don't want to shape kid's worldview, so to speak.
For those of you with tween kids, what do you think?
