I don't think it's just necessarily that word, at least for me... I think some SP enjoy it, but not all of us do. I don't think I'm a prude for not wanting to be called a bitch and other things like this during sex.. I don't like that in my personal life either.
I think a lot of practices are normalized because of porn but are on the kinky and dominant side of things, like very very rough sex, hair pulling or choking or slapping people's ass really hard, even face slaps or spitting or non consensual anal play. I don't think these acts are bad, I just think it's not everyone's cup of tea and it's better to ask before.
