Any ladies who do martial arts?

if you do, do guys a favor and STOP! ok, here's how it goes. i'm a guy, average height and weight. i went to the gym and saw this 1 girl doing stretches. cute! well defined tone and like 5'6. turns out she's 19, a sophomore at the junior college. i asked her what she was doing and she said stretching as a warm up for some martial art i can't remember. i busted up laughing!!! i was like "yeeeahh, right, you're a fmeale, that crap won't work on a guy!' and she's like "oh, really?" and she asked me to make a friendly bet, 20 bucks on a little sparring session until 1 of us said enough. i kept going on and on, so i couldn't say no, now i had to do it. so we put on the protective gear they have there, gloves and headgear, minus shoes. she really wanted me to go at her and take her down. ok! so the first thing i do is go straight at her, but she does some cute fancy HIGH karate kick in a circle motion from the outside in with her right leg and BAM! karate kicks my face, and i'm like sh**! but before i could react, she drops down QUICK and BAM! her right foot gives me this HARD kick right behind my knee and i dropped on my a**! so i get up and i have my hands up and she pivots from one foot to the other foot, doing these really fancy HIGH karate kicks at my face, BAM! BAM! left leg, right leg, left leg, and i'm like what the f***??? her flexibility on those karate kicks KILLED me! so i try 1 last thing, and i go forward to try to hit her and i had my hand down ready to throw a blow, and her left leg does a straight kick BAM! and karate kicks my hand away because i hadn't swing it yet, and then she does some cute spin and with her other leg, ANOTHER high karate kick in my face, BAM! and i fell down. OK, ENOUGH! I CAN'T BELIEVE her karate worked as easily as it did on me! she told me a lot of females are taking it now. THEN STOP! At least unitl i figure out a way to beat it. She was too damn good. I know 1 thing, if I ever need bodyguards, now I know! I'm taking 2 of these ladies that know karate, you can't beat it! At least i couldn't!
