A woman makes some sexual remarks to a man, and says she has a new lover and hasn't been able to get any sleep last night. In a very brief scene, a woman appears to be manually stimulating a man; this is shown only from the waist up with arm motion. It is implied that a man and a woman have had sex as they are shown together in bed the next morning.
An artist mentions what he likes in a model's "tits".
A woman's nipple is briefly visible while she breastfeeds an infant.
Many paintings (presumably actual Renoirs) show nude women alone or in groups.
At a speakeasy/brothel, men in drag are shown dancing together, and women are shown in underclothes with customers, but no sexual activity is depicted.
A young boy asks a woman to shown him her breasts but she refuses. Later, he sees her topless as she sleeps.
We hear that a man has had extramarital affairs.
On many occasions, there are leisurely views, some close up, of a woman, shown nude from behind and front while she is posing as a painting model. Only a couple of scenes of full frontal nudity, and those from some distance. Her breasts and nipples are exposed in many scenes.
In a longer scene, two female models pose for a painting nude from waist up.
