Somewhere along the way, society decided that women fighting was acceptable behavior, where it used to be taboo. My parents are still in the taboo category and I continue to have to hide what I do. Along with that societal transformation, some of the glitzy representations of fighting disappeared, and more realistic representations have taken over. Mud wrestling, oil wrestling, etc., went away, and real fistfights are now widespread between teen girls and women. They seem very popular among a minority of the population - maybe 20%?? My friends and I have talked about the fetish aspect of this and its certainly known to them. We are all late 20's to mid 30's. I have to assume that younger women are aware as well, since they must be seeing the same things we are. They might even be asked to participate in the fetish by fighting. Realistic fistfights in films, the popularity of women's fights in MMA and BKFC, and the popularity of women's matches in the WWE, all suggest that our fighting is now permissible and there is a market (even if a minority one) for watching us do it. I don't think anyone has ever done a study to find out why people watch us fight, but that would be very interesting to read. Some will have sexual reasons and others will have different, non-sexual reasons. But I am going to say, yes, as a heterosexual woman, we are generally aware of the fetish, just like we are aware of BDSM, roleplaying, feet, voyeurism and other kinks. We may or may not wish to participate in them, but we are aware of them.
