My feelings have changed as this seems to be a common term of endearment for a lot of people. If I hear 9 people called baby and one called sweetie, I would prefer sweetie. I hear a LOT of Tops/Dom(me)s say 'good girl' to their partners. I'll accept it from a play partner or someone I'm having fun with, but if it looks like it's actually going somewhere I'll let them know I would much rather prefer a smile or a touch or something else other than 'good girl' if I have pleased.
