J'ai voulu rire comme les autres (1980)

In one scene, six young boys are taking turns being washed by a woman in a bath. All are completely nude. Only one of them is sitting down so nothing is seen. Two of them are in the back with towels draped over their shoulders, still esposing their front. Three show clear views at their penises. One boy steps in the bathtub, spreading his legs frontally to the camera as he does so.
