Brandmale (1983)

A university student is torn between two very different women in the German drama Brandmale (Brand Marks)(1983). Robert (Hub Martin) is in a relationship with serious-minded hippie chick Angela (Anne Bennent), who expects her lover to be as fanatically devoted to her as she is to him. But Robert doesn't share Angela's ideas about true love, and is seeing sophisticated concert cellist Bettina (Gila Von Weitershausen) on the side. Then Bettina threatens to take their relationship public, forcing Robert to make a decision. Considering Anne shows T&A and Gila doesn't, as far as Mr. Skin's concerned (t)it's a no-brainer.
