Warbaby - I don't like sluts, in the "I sleep with lots of men" sense. I just like girls that are *my* slut. That one clicked a long time ago.

A simple choice of wording. I like the word sub just fine. But in certain... heated moments... slut has a lovely ring to it as well. I'd never call a woman a slut in public. Well, unless she was into that sort of thing.
