Blue Movie (1978)

Silvia is attacked but she escapes her attempted rapists and runs to the road where she is picked up by Claudio. He is an apparent mechanic, though we never see it, who is a photographer in his spare time. He takes her back to his home where she asks if she can hide out in case her attackers seek revenge, as she dispatched one of them with a rock to the head. He has a penchant for beautiful women, sexual perversion, and soda cans. He is also a misogynist who enjoys referring to women as half-wits when he's not coercing them into undesired sadomasochistic sexual relationships or locking them in rooms. Also he is a fond of fecalphilia. Throughout her stay in his home, she begins to fall in love with him, inexplicably. I guess she decides she can share him with the soda cans. But she has difficulty discerning fantasy from reality, so she is often hit with dream sequences which lead to her waking in fright. Another woman is, Daniela a model. Claudio is verbally abusive to her, who barely reacts to the ill-treatment. Leda is the third woman who he meets in a cafe. She has no money to pay for the coffee she has been drinking and offers the barista sex in exchange for payment. He settles her bill and brings her back to his place. The town Leda is from was destroyed by an earthquake, and she offers to do work for him, who makes her his secretary.
