Dirty Love.

"Three tales of sex and violence presented by TORO LOCO, a blood thirsty, perverted killer cowboy seeking and killing people that starred in some exploitation movie. He is showing his victims the movies before torturing and killing them with a cow skull. The first story deals with two inspectors hunting a cannibal serial killer called "The Tiger". The second is about a 'not-so-devoted' husband interested in having a night of perverted sex with a prostitute in a motel room. The third is a tragical love story between a poor, little man oppressed by his wife and an handsome boy with self-destruction tendencies.
