25 Days of Gays: I Am Guilty (2005)

The German film I Am Guilty (Falscher Bekenner) centers on Armin, a rebellious youth with no seeming drive for his post-school future. He spends his free time on sexual encounters with strangers in public bathrooms, and soon begins to seek notoriety and escape from his mundane life by sending written confessions to the police for a crime he did not commit, ultimately putting him on a path to ruin. Constantin von Jascheroff plays Armin and shows some partial frontal nudity while his character takes a bath, in addition to multiple shirtless scenes.
