Christina, the female fighter, says: "As a girl, I was always told how sensitive a male's testicles were; that these organs were a man's kryptonite. I had always assumed the pain was a bit exaggerated by the boys! I never realized HOW vulnerable male genitalia were until a couple years ago. I was play-wrestling with my then-boyfriend in bed. We would do this from time-to-time because it actually turned me on. We would sometimes wrestle as part of foreplay. I wore a leotard, he was naked. My boyfriend had a loose and long scrotum, so his testicles hung very low. I got a little overzealous and accidentally squashed his testicles into the bed with my knee! I could feel his balls so I jumped off instantly. He immediately curled up into a fetal position, holding his manhood in agony. I felt SO powerful! Most females seem to quite enjoy seeing someone getting whacked in the balls or otherwise suffering a "male injury". The problem is that guys on the receiving end usually find the experience acutely embarassing as well as painful - and nobody likes being laughed at, especially by members of the opposite sex. The upshot is that men frequently get upset when it happens to them, even accidentally, and women (especially as they get older) try to hide the amusement they get from seeing it happen. So a fetish develops. One of the reasons guys get so upset about a women hitting a man in the testicles is that the woman is intentionally injuring the mans sexual organs, his genitals, she is taking advantage of his being a male by injuring that which makes him male. In the process, yes, she is cuasing him severe pain. Nature gave us females much protection in our groin, in that our privates are very low and not really exposed. Nature did the opposite with males. However the weakness of the male groin is the great equalizer of the sexes, as males are stronger and run faster. The fact that some men fear females is a good thing in that most crimes are commited by men against women, not the other way around. And the next time you see a male rolling on the ground after being hit in the groin, you can tell your daughter what is happening, don't laugh, just tell her the power that she has and not to abuse this power over the opposite sex. Why don't you guys just admit females are superior for not having balls? A woman can contol a man anytime she wants with his balls. So why not ladies enjoy the power that you have over a man's balls. Nature gave it to you and us, so why not use it. The human female sex is superiior for not having hanging testicles. I actually feel sorry for some guys for having balls. They are so easily hurt. So men with this power of strenght should consider the weakness of balls, that women do not have. So who is weaker, the female that lives longer, or the male that has delicate balls?"
