Ok...he doesn't have to be a chauvenist to want to feel in "control" which is what he would be as the dominator. It's a mind game, a trust game....make sense? He can be the most wonderful man in the world and still want to feel in complete control, and have that feeling be a turn on for him.
From what I understand, for some people....BDSM can almost give you a "high" if you will from the feeling of power. Have you asked him how long this has been of interest to him?
