In the beginning, lots of conversations about sex.

A couple hides to have sex, but the woman has to pee first and the boyfriend gets killed before she comes back.

Another couple gets naked while drunk. Full frontal nudity from both parts. They kiss and have loud sex, but no actual penetration is shown, only thrusting. They get killed and their naked corpses are discovered later, only showing the man's behind.

A woman offers sexual services to avoid being killed.

After having sex, a bizarre couple discuss their fetishes. In another similar scene, they discuss how they discover their sexuality and a drawer full of vibrators is revealed. The bizarre man reveals losing his virginity to a corpse when he was young. They keep on talking about sex until they get into BDSM. No nudity in all these scenes, but they are barely dressed.

A woman undresses to get into the shower. Full frontal nudity, front and back. We see her in the shower afterwards.
