Sounds like a submissives form question, but I'll interject since it's not there.

You don't have to call a Dominant Sir or Miss in order to be polite. Please and thank you go a very long way. Even in the nilla realm. Asking a Dominant how they wish to be addressed would be a better approach IMO. If you were to ask me such a question, my response would be "call me whatever you feel fits, if Sir or Master are the title you view me in, then by all means use that. If you would prefer to just use my name, that is fine also."

My personal belief is that a person will view me as I am. I shouldn't have to tell them, nor do I have the right to tell them how to address me. Politeness works both ways as I see it. If you view me as Sir, Lord, Master, God, Oh Benevolent One, Your Highness, The Exhausted, Bastard, Asshole, Fucker, Sadist, etc etc that is the title you should use. If a person prefers to use just my name, ID or my first name (if we know each other that way), that works just fine too.
