Horror Hunks: Robert Floyd in Cold Hearts (1999)

Cold Hearts tells the story of a secret vampire war between murderous vampires and those that lead a secret, non-violent life in a quiet New Jersey town. Robert Floyd stars as Seth, a mysterious man who comes to town and falls in love with the non-violent vamp Viktoria, putting him into direct conflict with her ex, and the leader of the villainous vampire clan terrorizing and killing the town's residents. Robert gets a rear nude scene when his towel accidentally drops after Viktoria pays him a visit in his hotel room. It's a great embarrassment nude scene that shows off Robert's great body extremely well.
