jenny60, can I remind you that you said this:
I certainly wouldn't want him near mr my DDs if I knew he got off on pictures which simulate children.
Forgive me, but that sounds awfully like implying that OP's husband might not be safe around their daughters if he's looked at BarelyLegal. Why wouldn't you 'let your husband near' your daughters if you found a tasteless magazine? Do you think he'd sexually molest them if he wanked over a magazine full of 18 year olds dressed in silly outfits? What would you do, take out a restraining order?
If you found him with pictures of women dressed in 'naughty nurses' outfits would you telephone and warn the A&E department?
If he had a magazine with older women in it, would you think your mother wasn't safe near him and keep them away from each other 'just in case'?
Yes, I do think it's more helpful to tell OP that men are just genetically programmed to look at tits, bums and legs in any context (even outside a girls' school) than to imply that her husband is a potential child molester and might not even be safe with her children.
And how dare you suggest that because I think legal 'fantasy material' is Ok I would extend the same view to child pornography. That's a pretty offensive accusation, and a specious argument.
I have every sympathy with OP, I really do. But encouraging her to think of her husband, someone she loves, who is a good father and sounds like a good man, as an unsafe pervert is not good.
Men have fantasies that go beyond removing their wife's bobbly cardigan and making love to her. It doesn't mean they don't love their wives, that they aren't good husbands, good fathers or good people.
OP's dh was disrespectful because he brought this into their relationship by bringing into their home, but I really don't think he is just a bad man.
