@AtYourPleasure : Well, I'm not one of those men. I love my wife, think she's beautiful, and I respect her. When you posed your question(s), you seem to be promoting the idea that a connection with a person outside your marriage isn't a true connection, and that if you seek sex outside your marriage, then it's just a physical act. Now, I have no direct experience of that but I know we can get true human connection outside our marriage in various forms, so why not sexual connection? The older I get, the more I think monogamy's maybe a terrible idea.
One night, within the last year, I was feeling utterly dejected, so I decided to go out. Got the train into my local city, went to a pub in a rough-ish estate and, when I was getting back on the bus into town, the (male) driver gave me a friendly nod - and, by god, how much I needed that connection with another human being at that moment. That's all it took. It was like, "I see you, bro."
Like most people, I have filthy and depraved thoughts (Psychologist to client: "Are you troubled by depraved sexual thoughts?" Client: "No, I quite enjoy them) but a lot of my need for sex is to lie naked, in contact with a woman who accepts me as I am. My wife rejecting me sexually is rejection of my being.
Mumsnet is primarily a women's forum, and I respect that, and if I was kicked off for being male, I'd say, "Fair enough, it's been great." When I read of a woman in a sexless marriage who loves her husband and finds true sexual connection outside her marriage, I'm happy for her. I don't think of her as a sex pest. It's the same for men.
