I can pretty much relate to all the reasons on this thread.
I've not had sex with my wife for 15 years, as soon as she found out she was pregnant with our youngest the tap was turned firmly off!
I tried to talk, followed the advice of every feminised, pussy whipped advice column I could find (why don't you reward your wife for her unreasonable behaviour?) and hoped she would come around but after a decade of internet porn and excuses I decided I wasn't going to live like a monk because someone else had decided that fate for me.
BTW surely using sex for control in a relationship only works if there is a realistic chance of getting some?
So I told my wife, if she isn't interested I will go out and pay for it (still can't quite believe I said that), she didn't say anything (she didn't talk to me for a while but she didn't ask for a divorce either) so off I went.
Since then I have met about 40 different women over about 50 meets, had a dozen massages and been like a kid in a sweetshop.
I'm sure she knows what I get up to (I went "swimming" a couple of weekends ago, came back with a dry kit and smelling of perfume!) but as long as I don't humiliate her (or pester her for sex) I think she's happy for someone else to take care of things.
I love the research, the notification emails from AW, the first sight of the girl behind the door, punting with women who wouldn't look at me twice in civvie land and blanking the fat, saggy divorcees I work with who seem to think they are Cindy Crawford because I've had better on a bad day!
I've done so many things I previously couldn't even dream of, CIM, DT, anal, sloppy blowjobs, threesomes.
I realised the other day, I finally have the marriage I want! Don't want a divorce, to lose my house or go back to the snake pit that is the dating scene.
