Lots of sexual conversation.
Barbara Streisand's character Doris wears a lot of sexy revealing outfits often showing ample cleavage. One outfit has images of hands on the breast part of the outfit and another time we see her in a bra. Briefly a few times you can see a small part of her butt sticking out of her underwear.
A man puts his hand on Doris' knee and is later seen paying her in her apartment indicating that he is a john.
George Segal's character Felix goes to a dirty movie called "Cycle Sluts" and we hear some risque dialogue from the film and we see audience members leering but we don't see the actual film.
A sex scene between Doris and Felix in which we see much kissing, clothes being removed(no shown nudity) lots of movement(but nothing very graphic) under a blanket, moaning and suggestive dialogue, rolling around, and limbs flailing.
Doris dances suggestively in a gentlemen's club and a man slaps her on the rear.
A group of men are seen looking up a woman's skirt(we only see legs however).
Doris and Felix kiss and start to remove each others clothes in bed. The scene ends there implying that they had sex.
Doris and Felix sit naked in a large bath together(no seen nudity).
Felix shows his penis to Doris early in the film(nudity completely obscured by objects.).
A brief non-explicit shot of a sex magazine called "Screw" at a news stand.
A man invites Doris into his shop to have sex. We later see him in an undershirt and boxer shorts. Doris leaves without having sex with him.
We see another couple in bed kissing(they are clearly naked under the blanket but we don't see the nudity).
