For me, the turn on is words and phrases that only he can use and get away with, words that define his sole proprietorship over me: being called his slut, his naughty little girl, things like that. All those things are states of being only for my Dom, and that makes them exclusive and special instead of degrading.

Being humiliated by being called stupid or worthless or names in a similar vein hold no draw for me whatsoever. Humiliation like that doesn't even have a vestige of truth, it's simply mean and does nothing for me.
