*Adding this: I would ALSO see what his internet/online "habits" are too... I would certainly HOPE he is not having a PROBLEM with this, of viewing UNDERAGE GIRLS, online either. He really seems to have a problem. Sorry, but this is my opinion. No man in his right mind, would see CHILDREN much less his own or others, in a "sexual" way...where they are "oogling" other girls in this fashion....AND other people notice too.... this is a hint that it may well be a problem.
Well, that is just creepy. AND, other Moms even pointed it out to you... that he was checking out UNDER-AGED "girls."
I would speak to him... tell him OTHER people notice too... so it's just not you, a wife, 'complaining.'
He HAS TO KNOW that this is creepy and in appropriate. I would certainly watch how he views your daughter, especially as she gets older. And speak to your daughter about "proper" behavior... in light of voyeurs etc.
Sure, he's turning 40...but this is NO excuse. Make sure it does not escalate....
Some people just see CHILDREN in sexual ways... and checking them out, in such a flagrant way like this, is really creepy.
Sure all men look at other women.. but this, the way your Hubby seems to "look" seems yucky... and inappropriate. He best CURB this, before some other Parent accuses him of something or worse.
I suggest talking to your Husband, observing him, seeing if there is a 'bigger' problem. Even counseling.
All the best,
Susan
