What to do ?

What 14-y.o. boy wouldn't be curious about the female anatomy? Gays aside, I mean. It doesn't make him a perv and it doesn't mean that he wants to have sex with her. If he's promised not to do it again, that should be the end of it, as long as he keeps his promise. There's no way to go back and undo what he did.

CALMLY tell him that you know what he has been doing and tell him he must stop because it violates someone's privacy. Then block the peep hole.

Then ask him if he has any questions about women and their bodies. Perhaps he needs to look at some pictures of naked women.

He is at his peak of sexual curiosity and women both baffle and fascinate him. Try to be calm and informative instead of over reacting and shaming him.

(He probably would have done this with a sister.)

PS - have you had "the talk" with him? Be sure to include permission to masturbate - in private.

Clearly the 14 year old should not be allowed to do this. Any 14 year old knows that what he did is wrong. Deal with this like you would with any discipline problem. Find appropriate punishment. When the punishment is finished, you move on. This isn't the end of the world, but what he did is clearly wrong.

You should understand the feelings of your wife. This is a violation of her rights. She has the right to be angry, but if the family is going to work, she needs to get over it. You might want to give her some time, but she needs to handle her feelings. The step-mom does need to act like an adult in the family. But personally I would be pissed if this happened to me.

If this is damaging the family, it might be a good idea to get counseling.

This was with the stepmom, not the real mom. That doesn't make it any less of a problem, but puts things into perspective.

I don't know which perspective you mean. If you found out that a teenager was spying on you while you were in the shower, this wouldn't upset you?

Most people would be very upset if this happened to them. I think people here aren't being fair to the wife in this story.

I assume he's apologized profusely to her, and if he hasn't make sure he does so immediately. Also if you haven't punished him, do so immediately.

I don't blame your wife for being creeped out, but it's not a sin so great that justifies her never having anything to do with him again.

Give her a reasonable amount of time to get over it. If your son is otherwise a good kid, it will eventually blow over.
