This seems to be a personality characteristic, ie. some people only want/desire what they can't have. I was wondering the exact same things as you expressed, and I also worry about the dynamics of this in the long run. I thought it was odd that a few weeks ago, my W got horny about 2 hours after I blew up and told I wasn't going to be satisfied with MB and things needed to change. Not a "I guess I better pretend I am for the sake of the R" response either. Go figure. But we went back to the same old shortly after.
