He usually calls me wench. During sex he often adds dirty or horny in front of it. I like being called wench, even if i think i don't really understand what a wench is (he's American and my mother tongue is german. But we usually communicate in english because my english is much better than his german)
I just know that vanilla friends who are english spoken thought that "wench" isn't very nice. So i guess that the term has an underlying meaning for some people i didn't get yet. But i don't care too much. It's special and he's the only one who uses it and that's probably the reason why i like it as much.

And then i get called a lot of other things too, if things are getting hot.

There is just one word that i can't stand, and that's "cunt" and its german counterpart "Fotze". For me that's just too derogative, and are terms used by people i absolutely detest (i'm not talking about people in the lifestyle but about guys who use those terms to depreciate and objectify women)
