What new turn-ons/kinks have you discovered from romance novels?

Stuff that you never knew you liked until you run across it in a book and you're like... oh shit. I'll go first:

-being called a good girl: holy hell guys. Gives me those butterflies in the stomach something fierce

-biting. Nuff said

-tails. Anytime I read a romance with a mc that has a tail I'm like DO SOMETHING SEXY WITH IT

Your turn folks, spill it!

EDIT: A big one i forgot: weird dicks. Give me all the ridges and bumps and prehensile bits and parts that vibrate and odd shapes
