I always appreciate, being called, a friend, or Companion, or Provider. I don't mind being called escort either, but the other names sound more discreet to me.

No prefence on the 3 you mentioned... But I never refer to clients as "clients" or "customers" . I prefer to call you gentlemen my friends

How about calling me by my name, "Carla" When you are at your job people call you by your name not your profession... ie
Fry Cook John Smith, or Maid Jane Doe, just doesn't sound right. I like to refer to my clients by their names, not by what they do. Now if you want to refer to me by what I do just say I'm one of the best GFEs. Have a great day.

XOXO
Carla Brazil

Re:Providers… What's your preference?

I don't mind any of the above although I prefer "Friend" as well. It is more discreet after all. I do catch myself on occasion calling you Gents everything from  friend, gent, client, hobbiest etc. I think it really does depend on the situation.
