Equation to an Unknown (1980)

One could argue that Equation to an Unknown (1980) stands as the masterpiece of Gay erotic French cinema.  This film stands the test of time in the adult entertainment world and holds up surprisingly well in comparison to it's American retro porn counterparts because this film is primarily a story driven erotic adventure, instead of a series of fuck scenes strewn together with comedy or well timed "pizza deliveries".  In Equation to an Unknown, we follow a young man, Gianfranco Longhi, venturing out into the world on his motorcycle, trying to break away from his mundane existence by traveling abroad and jumping from one hardcore sexual encounter to another!  He sets out as a stray dog amongst the wolves of France and much like hungry and horny dog, he never seems to be satisfied with one encounter and his lust and libido keep driving him into a road trip of one off encounters with strangers in locker rooms, bathrooms, and even getting busy in a good old fashioned orgy of French hunks.  This classic is a legit erotic arthouse film, punctuated with real hardcore sex scene throughout that actually have incredible mise-en-scene and paint an excellent portrait of a man lost in libido at his sexual prime!  Star Gianfranco Longhi along with a bevy of boy toys like Tony Weber, Jean-Jacques Loupmon, Reinhard Montz, Djalil, Jamie Sutherland, Dominique Delattre, and Jean-Marie Descamps all have real sex throughout this classic, and with it's solid story, arthouse cinematography, and incredibly sexy cast, it is still bound to bring about an "answer" to the "Equation to an Unknown" growing in your britches!!!
