In this movie...

Paul Hopkins is seen naked on the bed after making love with a man. There is an extended view of him, moving on the bed with his dick and balls flopping around. Whip Hubley is then seen naked entering an isolation tank. After seeing his muscular torso we get a very good close-up view of his ass, and then as he climbs, we see his balls and dick. His balls are pretty big. Finally, we get to see Billy Campbell naked. There is one scene when he is lying on the floor next to Paul Hopkins. Billy's balls are huge. So huge that when his dick was hidden behind his balls when he was on the floor. Luckily we get a glimpse of his dick as he stands up against the bed. All three actors are circumcised.
