Flesh (1968)

Geri (Geraldine Smith) ejects her husband Joe (Joe Dalessandro) from bed, and insists he go out on the streets to make some money for her girlfriend's abortion. This leads to Joe's various encounters with clients on the streets of New York City: an Artist (Maurice Bradell) who wishes to draw Joe, a Gymnast (Louis Waldon), and another 'John' (John Christian). Joe spends time with other hustlers, one of whom is played by his real life brother, and teaches the tricks of the trade to the New Hustler (Barry Brown). Back home, Joe interacts with his real life one-year-old son. Joe gets back home, presumably at the end of his duty work, and is in bed with Geri and her girlfriend Patti (Patti D'Arbanville). The women strip Joe and begin to get intimate with each other; Joe gets bored and falls asleep. (Source: Wikipedia)
