It’s a color movie, but older, I would say 80s or 90s. I believe it was a foreign film (German or French perhaps). The scene I’m trying to find was with a boy laying on the floor flipping through a magazine of topless/naked women and masturbating. You did not see the boy naked, but his face was shown (while his body shook, implying the masturbation). He finally had an orgasm and he was touching the women in the magazine. Thanks for the help!
