I suspect the misunderstanding might be around the precise meaning of the word "kink" then.

I think in one common understanding of the word, that I assume the OP was using, having a taboo fantasy that you merely roleplay with a partner you are deeply intimate with, in full consent from both, can very well be classified as "a kink", even if what you're experiencing is the not really SA.

Based on your response, I'm assuming that in your understanding, it would only be "a kink" if it was a desire to actually experience a real sexual assault, which of course no one, or perhaps only an extreme extreme minority, actually wishes for. I don't believe OP meant to imply that this is at all common.

More like if it’s a desire to have a consensual non-consensual encounter, a sort of kayfabe at the least
