To me this is really repulsive. I can't understand violence at any level in sex. I am so gentle that one time a provider asked me to choke her as we were going at it. I couldn't do it. Later in the session were were in doggie and she wanted me to spank her. I did, but it made my dick go soft.
There are some kinky things that turn me on, but anything that could hurt a woman is a big turn off.
