In the catfights I have tried to setup, we develop of list of allowed and not allowed attacks. The not allowed list is usually dangerous attacks that are a turn off for me (biting, scratching or any nail attacks, eye gouging, choking, smothering, joint locks, head or neck punching, head banging, any attacks that draw blood or break bones). I like competitive fights but I don't want to see anyone seriously hurt.
I have a list of things that I like to see in the catfight but the ladies decide mutually what is allowed from here (hair pulling, face slapping, body slapping, breast mauling, face sitting).
