They push the envelope nowadays, with nudity ajd profanity.
There was a time when bedroom scenes wouldn’t be shown. They might be hinted at, but not shown. An example is the movie ,”A Thousand Clowns,”,in which the woman love interest of the Jason Robards character was still there with him the next morning, but they never showed them in bed together. They didn’t explain why she was there the next morning, it was just implied she spent the night.
Or in Urban Cowboy, John Travolta went to the apartment of a lady, they had her open the door to her bedroom, and that was the end of the scene. It was pretty darn clear that they were going to go to bed together, but they didn’t show John and the lady in bed.
Interesting that you remember those scenes.
