Why when a guy slut shames a woman he physically assaults her?

I told a guy I had sex with a guy guys before him because he asked and he did not take the well. He called me disgusting during sex and strangled me during sex. This never happened to me before and I am traumatized because of this. Should I have called the police? Why do some guys act like this? I don’t deserve to be treated this way because I have a lot of sex.
