professional mistress 

An upscale prostitue who services a small number of men (usually executives) on a regular, long-term basis in exchange for them contributing to her financial well being. Each man may call on her anytime on his regular day (eg. 1st & 3rd Tuesdays). If he needs her for a Friday,Saturday or other days, additional negotiations are necessary.

I could never be a protitute - having to hustle for johns and taking risks, but being a professional mistress is great because I am in control of who I see and when, and the guys I pick really take good care of me.

Dairy mistress

When dating a vegan, you're likely to not eat animal products when eating dinner with them. However, you likely eat animal products when at dinner with a friend(s) who is not vegan, and this friend(s) is/are your dairy mistress(es).

If your partner is vegetarian, the friend(s) would be a meat mistress(es).

Bob: Dude, I totally couldn't eat this grilled cheese if Susan was here; she became a vegan 6 months before we started dating. You're so my dairy mistress.
