I have given this a lot more thought so let me expand my previous answer.

Mostly the ones that I have had as slaves are intelligent professional women. If I am out in public with her and I am not upset or very elated with her it is lady or my lady, if she has been a bit of a brat its sexy, wench or sexy lady, if it is meant to put her in the correct mind set its MY LADY or MY LITTLE GIRL.

When we are alone or with those in the know it slave if I am upset with her or my slave when happy with her. Alone it can be my slut, my wench or what ever I think will get the response I want.

To call her bitch any where or her given name means I am very pissed with her behavior this I use rarely.
