for me I have never done it before but I get turned on watching it, maybe its the humiliation of a stud getting defeated, "owned" by a cockier, more "macho" man??.....I remember getting really hard watching the fight between Meerschaert vs Chimaev....the little guy KO the bigger hunk in less than 17 secs, and the big muscled stud went down totally unconscious after just one punch, after all the crap that he was posting online....sweet!!!....on the other hand I liked Meerschaert and I wanted him to win.....weird!!!....I wonder if I should go and see a shrink....LOL....
