I'm not going to even participate in this poll because I think it's irrelevent what the general public thinks in relation to what you and your wife do - I also think you enjoy this whole idea of the posters telling you what to do LOL - since you like being told what to do.
I agree with Maven and Crystal this kind of behavior should be decided between you and your wife. The sado masochistic behavior should be looked at as role playing that is used during sex and not used to influence your whole lifestyle - where she would be dominating you completely. If you're seeking to be dominated completely then I think you should see a counsellor. It's also very important that you never actually get hurt and that your wife is agreeable to participating in this way. The bottomline - if you both happily agree to use this as part of your sex life(where neither of you is hurt physically or emotionally) then it's fine but it shouldn't influence your whole life. Good luck.
