I don’t remember much of the movie but one scene. There was a character(male, 16-25) who was played by a fairly well known actor. He was sitting on a couch(red and circular I believe) and was watching an adult film or something to do with breasts. I can’t remember much else but this and that I saw it a few years ago and it was futuristic
Perhaps “Closer?” https://www.youtube.com/watch?v=iCfBiIzWG9g
