All those other cute names you mentioned, you'll never hear come out of my mouth.......

My civie lady friends I'll call those names, but I refuse to call a girl I pay to f*ck my "babe" or "Hun"

Don't lose sense of the game at hand, these aren't your girlfriends

You do realize that "my love" in Vietnamese means

ATM

Also translates to john

name

'baby' or 'lover' usually works for me..

I will invariably know their real name.  In private, I use that.

In public it depends--is it a "professional" date or a "friends" date?  Where are we, who are we with, etc.  But generally to be safe I don't use any names in public, nor do I use "babe", "honey", etc.  Discretion is a practiced skill.

their name or something similar to what a character like The Duke or Gus in Lonesome Dove would use but never in a million years would I say "boo". That word drives nuts. To me it's almost as bad as  " Baby Daddy ".

OK, seriously, I call her by her name if I know it.  I try to avoid babe, sweetie etc.  Sometimes with a regular a nick-name just sorta develops.
