What pet names/terms of endearment/ nicknames/titles do you like during sex?

Are there ones you love, or ones you’ve instructed your partners to use (or avoid?)

Which ones take you out of the moment?

Are there ones that male you feel good or bad when you use them on other people?

Moreover, how did you discover these reactions? Was it all trial and error during sex or did you see/hear/read one and decide you’d like to try it?
