Throughout the film, there are a few sex references, none strong though.
A woman kisses a man, licking his face and lips and moans.
A man and a married woman kiss a couple of times.
A man is shown running while in briefs, and a man in shown walking around in his briefs.
A poster of a woman in a skimpy bikini is shown hanging on a bedroom wall.
Two men talk about a woman being "hot."
A man flirts towards his female therapist who rebuffs him but towards the end. It's hinted that they're dating.
Extended sex scene in bathroom. Nothing is shown, but character dialogue, motions, and sounds are very explicit.
A man rubs his balls on a drum set and everything is seen up close including his balls. Strong nudity in this scene.
Two men are shown peeing in the same toilet at the same time, and you could clearly see their pee coming out. They end up trying to have a "sword fight" with their urine. No nudity.
Outside of a few explicit scenes, most of the sexual material here is through verbal references.
