This movie explicitly depicts several sex acts in multiple scenes including breast groping, fellatio, cunnilingus, and manual genital rubbing. Heterosexual intercourse is implied but not actually shown. Each of these acts is done in couples only, either straight or lesbian.
No external part of the human body is hidden in this movie. This includes clearly erect penises and exposed labia. Most scenes in this movie either start out showing some amount of nudity or depict a character undressing later in the scene. All of the main cast actors are shown nude at least once, sometimes in company with clothed characters.
In several scenes, we see up a woman's skirt to her panties. In a few of these, we see clear pubic hair and possible labia majora around the panties' crotch.
A woman dances in a night club on stage in sheer lingerie. She removes her brassiere and panties, exposing her breasts and full natural pubic bush. A man wearing only an unbuttoned dress shirt joins her on stage and performs several explicit sexual acts with her. We see no explicit penetration or ejaculation in this scene, nor any other scene within this movie.
A man masturbates in public with onlookers. He is fully dressed, only his penis showing through his trouser fly.
Two women wake naked in bed together. They dress and leave the apartment. Later, they partially undress each other at night in a public park and engage in heavy petting.
A woman in an electronic dance club strips to her panties and dances among the other patrons.
A woman completely undresses in two daylight city scenes, leaving only her high heel shoes on each time. She is evidently not caught in either instance. In one of these, she urinates from a standing position, the camera angle and actress' posing hiding nothing.
