Everyone fucks. I don’t need to see the details about that aspect of most characters’ lives in order to understand the story being told about that character. I love sex scenes. I hate sex scenes that are gratuitous and don’t enhance my understanding of story or character. If it’s not needed for one of those things, it doesn’t belong in the story. (and that’s true for any kind of scene, not just sex scenes)

If the purpose of the sex scene is “you get to see this actress mostly naked” and no other purpose - then yeah, that feels cheap and gratuitous. Make a movie where her sex life matters if you want to show me that.
