Heat Wave(1977)

Dante, a real-life Times Square Magician in the 70s, offers the narration as Scratchit- otherwise known as Libido. Libido is the little voice inside your head that connives and drives your sexual impulses to the point that you will make the wrong choices in order to fulfill your sexual fantasies. The trick is living with Libido, and your choices, for the rest of your life.
