The sex scene in this movie is in no way mild. It's in the same vein as late-night adult films on cable.

There's a "morning after" scene immediately after the sex scene. Both are still nude and both of their bare chests are seen.

Detailed slow sex scene in many positions with her breasts and butt displayed prominently, and his butt is visible.

Later on, a couple wakes up in bed together wearing only boxers/panties and they get out of bed. Her back is to the camera.
