Puberty?

Well, I was cleaning Christian's room....I found several pages torn out from magazines with women wearing bikini's and bra and panties....Isn't this kinda soon? Hubby had a talk with him about it, got him to admit he liked the girls and was curious. Where did my baby go? He is only 11!
I told dh we oughta put up a poster of a girl in his room (fully clothed) and see what he does...he would probably hate it. Could you picture a mary kate and ashley picture on his wall...LOL.
I am guessing I have to hide my people magazines now. :-(
