People all around the world, both female and male enjoy boxing and wrestling, a good catfight is infinitely more appealing to me. I'll admit I find boxing a bit dull to watch, the idea of doing it is far more attractive than watching it, wrestling can be fun to watch, I know it's pre-arranged but to me that doesn't make it any less enjoyable as a spectacle it's pretty damn impressive what they pull off to entertain people. A lot of people just like watching fights so we really shouldn't forget that when talking about the appeal of catfights.
As for catfights a big part of the appeal in watching a real one is that it is completely real, anything could happen and that is pretty thrilling even though an actual fight really doesn't last long in my experience. There is also the fact that because it is a real fight it represents a genuine instance of people being able to free themselves from rules and all that baggage that makes us different from other animals and just do what they want. To me that is massively attractive, just being able to do what you what fuck the rules, fuck what is expected. Heaven!
For me it is that point that I think might result in women enjoying catfights more than men. I imagine deep down most guys would like the ability to just let loose and punch someone if they pissed them off? Isn't it in all of our natures to be competitive and somewhat adversarial? A real catfight is an opportunity for us to do that, there is of course also the huge thrill of winning which I think is intensified from coming out on top in a one to one physical competition with someone you really don't like, whatever your motivation.
For scripted catfights, well, who doesn't love seeing two attractive people beating up on each other? Oh no completely occidentally all of their clothes have fallen off, darn.
