In fantasy? Being made to be naked at a party, being passed around. Being turned out. Kneeling at the side of my guy while he talks, not being allowed to talk. Serving, yes?
I don't love love any of that IRL, more into being valued but it sure is a turn on in literature & fantasy, I have done some of it and enjoyed, if my partner enjoyed. I think the only time it's a turn off is when women are interchangeable, that's bleh.
In reality the only things I actively like being humiliated around are the things I don't mind or am happy with, like my complete lack of control. Stuff I'm pretty confident about.
