@OP
While I was with other they left it up to me to use the term that best fits that person. Whoever I was talking with, as long as they showed that they were worthy of me talking with them. Not everyone deserves to be called "sir, ma'am(i dont call females ma'am)", I will show them respect because that was how i was brought up, how i was raised as a child. My mother always, always, always wanted me to show respect to everyone, just because i am submissive and with a dominant male, doesnt mean that i forgot out to be polite or sweet to other. Now if i was with someone wanted me to use those terms, then we would really have to speak about it. Not everyone deserves them so i rather use their nicks, or their real names.
