Spice

I often see people say things like, “Xyz author’s spice is not my favorite” or “I love this story/plot/idea/etc but hate how they write spice.” For those of you who dislike a popular author’s (possible examples: Maas, Armentrout, Hazelwood, etc) depictions of sex, why? What about them do you dislike?

I’m just curious. I usually don’t have strong feelings about it unless they’re just so generic they’ve become boring, so I don’t have a lot of skin the game (pun intended). But as an amateur writer and student of social sciences myself, I’m always curious about why people dislike something that is otherwise somewhat popular.
