In the Unrated version a man's scrotum is shown as well as a woman's very full pubic hair which was a merkin shown for comedy effect.
Most sexual content is based solely in dialogue. The only exceptions are flashes of limited pubic nudity: a scrotum and female pubic hair.
A confrontation happens where two former partners criticize each other's sexual experience to each other in detail.
A character unexpectedly walked in on a bottomless male as part of a prank later to be revealed to be an ongoing competition. Only the back of male legs can be seen.
Two characters have sex in a bathroom stall. Nothing graphic, both are clothed, but they are sene moving together and the woman is rushing him to climax. It's very short and played for humor.
A character flashes back to a trauma of another man peeking at his genitals while using a urinal beside him. Both characters in the flashback are seen from the perspective of the wall the urinals they're using. One is obviously peeking at the other.
Multiple adult characters openly flirt with an explicitly underage girl.
Important Note: in the "Unrated & Raw" Version of the film, there is a scene where a guy and a woman are completely naked.
Throughout the movie, male employees at a restaurant play a game in which they try to surprise each other by making one another catch a glimpse of their penis or scrotum. This is a major theme throughout the movie and is referenced multiple times. Later in the movie, there is a flash of a character's scrotum, whether real or prosthetic. Following the theme, at one point a woman flashes her pubic area, which is seen in two different close-up frames. She's covered with a dense merkin (fake pubic hair).
There is a long discussion of the "game" mentioned above being super gay.
