I don't think so. I think one could be a Call Girl Genius.
Almost certainly true. Somebody famous once said that men always treat their mistresses better than their wives. I think that is probably valid even for single men. That's why I'd rather have a lover than a boyfriend. Why should I go to the seriously grievous trouble of trying to domesticate a wolf when all I have to do is pin a bunny tail to my monkey *ss (right where it would best accentuate my .7 waist to hip ratio) and give a little shake and I can get all the carrots and bananas I could possibly want?
