The movie has a lot of full frontal nudity, and a few sex scenes. Although the sex scenes are not very explicit.
There are a couple of vigourous and loud sex scenes in a bath tub with very little actual visible nudity, as it is shot from above.
There is a scene of a female character sleeping in a bed with 3 male characters, and then briefly fooling around. Full frontal nudity from both, but the penises are flacid.
There is full frontal public nudity but it is non-sexual.
A female character photocopies her breasts and pubic area and leaves the copies there.
