Re: Too young to masturbate?
I wouldn't even mention it to him, personally. At 12, he's going to be mortified if he thinks you know, and he definitely knows that it's something to be done in private. I remember starting that at a much younger age, and I'm a girl! 12 sound like the prime age to me.
I too would talk to your wife. I have a DS myself, and dread the day I catch him "growing up." Another thing, I would give him the birds and the bees talk if I hadn't already, but I don't think I'd let my wife do it. Parents of the opposite sex will completely embarrass a kid at that age. I think most kids like to think their opposite sex parents are ignorant to what they are doing. My DH and I have an arrangement where he will handle all the man stuff, and I'll handle all the woman stuff when that age comes. It only makes sense, IMO.
