I grew up during the time when sex scenes on HBO and Cinemax were the closest thing to porn on tv. I can’t think of a worse sex scene than The Specialist, with Sly Stallone. It was silly and unnecessary. I even found it weird as a teen. That says a lot. There were many scenes like this in many films.
You can include sex without dramatizing / showcasing it. I don’t blame young people for finding these old tropes to be a digression. See my other comment about sex in The Sopranos to confirm that I’m not anti-sex in media.
