Robert Pattinson hangs out with Javier Beltrán. One night they are both swimming in their underwear and with the under-water camera, we can see their bulges. Then they kiss each other and it's very hot. We see them kissing again a few times after that.
26 minutes in the movie, Jonathan Watton is naked in bed making love to two women. When he leaves the bed, we see his butt. Then he sits in the chair and we see his penis. He then masturbates briefly watching the two women.
