Godless Youth (2017)

A young man has an affair with a young lady. They are shown kissing a few times and they have sex a couple times but no nudity is shown, only movements and sound. The man touches the woman's breast under her clothes but no nudity.

A man is shown sitting up on his bed and in the background a fully nude woman can be seen asleep on her belly. It's implied this is the aftermath on sexual intercourse. Later on the camera angle changes and this time we can see her indeed fully nude, her buttocks shown clearly.

Young man shown showering from the chest up only. Later on he comes out of the bathroom fully nude (shown from the waist up). A maid comes and helps him get dressed. There are mirrors in the room and we can see his nude image on one of them, penis shown, but this is very brief, blink and you'll miss it
