What kinds of things do you feel comfortable or uncomfortable saying?
I’m a big fan of being on the receiving end, but sometimes I get a little uncomfortable. I had a partner who I know started believing what he was saying near the end of the relationship, and blurring those boundaries really messed with my head.
I’m a big fan of being told that I’m not intelligent - “dumb slut” etc - because I know that I am actually smarter than most of my sexual partners IRL but like to be a brainless fuck toy during the act.

Well yeah but it can be a lot more like forced or unpleasant/awkward positions. Or being “manhandled” or better being made aware of being bodily inferior. Or having to wear stuff that reduces your body functions like Chasity cages/belts or beeing collared in public. That’s just from the top of my head like I said humiliation is pretty personal so what isn’t humiliating for one person can be very humiliating for someone else.
