The problem with mixed matches is that the results are always skewed in the woman's favor. Every mixed match I've ever seen, with the exception of a few (DT matches with Puma in them being a notable exception), always ends with the woman winning, because it's almost always some pathetic balding loser who wants to get beaten up by a girl. In reality, if it were an actual match, probably no more than 1% of all mixed matches would end with the woman on top. Barring an overwhelming gulf in skill (and the average woman in these matches is no more skilled than the average man), the woman has no way to overcome the man's superior strength. Now, she might be marginally faster or marginally more skilled, but it takes a lot more than slight differences to bridge that gap. That's why I avoid mixed matches like the plague. They're all fake.
Are you kidding me hun? A girl and a guy of the same weight class, same skill, same training, same sames across the board, is going to end up as a tie. A guy is marginally stronger and a girl is marginally faster (and definitely more flexible). Depending on their background, that could add to the difference. For example hun, my childhood/early teens was spent in not quite the ghetto/hood/projects/etc. I explained it somewhere else, but two girls fighting is a lot more aggressive than two guys fighting. I can't explain it simply. From my point of view, guy fights are simple and straight-forward; the winner is the winner, doesn't matter if you only just won, you won, Pass or Fail. For girls, it's so much more than that (and I think guys don't understand that because in most of the FvF catfight/sexfight/wrestling stories I read, all the subtext is missing). It's... I don't know where to start hun, but the best way to explain it is that women are like cats, men are like dogs.
If anything, in a NHB fight at equal skill level, women have the advantage.
Now for me I'm a little different hun. I'm above the average weight class, skill level, and training amount then most other women, putting me well above the average guy. I've fought a few 'jobber' guys, more in it for a free grope then the match. But I've fought musclemen. Guys who couldn't understand the idea that a woman could be any good in a match. Guys with a chip on their shoulder to PROVE that a woman COULDN'T be any good in a match. Like I said, undefeated in mixed fights.
