Typically I prefer if sex scenes tell us something about the narrative, themes, or characters. It feels dated to just have a scene that only serves to titillate the audience. Like from a generation that was averse to porn consumption or access.

I absolutely don't mind if a couple of actors can tell us something about their characters though sex and nudity. It's part of being human, it's part of storytelling. But the show should be about something or I'm just gonna get bored.

That being said, some older movies were spectacle first, light on plot, heavy on nudity and sex, and were meant as light entertainment. They often crossed lines of taste, so not for everyone. Kind of a dead genre, exploitation. I'm an age where I can still appreciate it but often hit a wall of ick and discomfort over badly aged tropes.
