Since the comments here seem to be mostly like "well at least some of them do", I'll just go ahead confirm your suspicion as a woman who has talked to other women about their relationships. Liking to be denigrated is not the norm at all, it's kinda gross and demeaning. However, much like many other sexual practices that many women find distasteful, some women will play along or pretend that they're into it to make their partners happy. Most of the time the partners aren't trying to be controlling or whatever, they're just imitating porn which normalizes that kind of thing. So yeah, there's a high chance this was a one-sided fantasy like you suspect.

> woman who has talked to other women about their relationships

That's less relevant as actually having sexual encounters with a woman. People often don't know their close friend's fetishes, but they do (or should) know what their lovers enjoy.

For a counterpoint: open a book of women's fantasies written by and marketed to women.
