What’s the name of this movie?

I remember a movie where the main guy is a total predator—he spends the whole film taking advantage of and exploiting different women in various ways.

There's one particular disturbing scene that stands out. He demands that a girl perform anilingus on him (eat his azz), but she flat-out refuses. He then forces her to do it anyway against her will.

By the end of the movie, a different woman who has been actively searching for or hunting him down throughout the entire story finally finds him and kills him
