Hey im dan, im 20 years old, i train martial arts for few years and i have big muscles (6packs etc..). Im 5'5 tall (1.65).im from Israel, I have 3 black belts (krav mgaga karate and jodo).
Yesterday a australian girl arrived to our class. She is just 16 years old. She is pretty tall (1.74) (5'8). And looks very good and attractive. She is knows as one of the best of the best fighters on earth. She has 6 black belts.
When she arrived in our class for 1 lesson it was a great honor, after the warm up we asked her who she wants to fight against. She simply said "i want to fight vs your strongest man here" and it was me.
So we fought 5 rounds of freestyle. She won them all very easily! She is amazing.
After the 5th match she helped me up from tge floor and after the lesson was end she talked with me and she said i was very good and complimented on my muscles.It was an honor to be complimented by that legendery young fighter, I also complimented her alot.
She asked if i want to train with her while she is in Israel. I agreed.
I have 2 qwestions.
1-should i feel embarresed that a 16 years old pretty girl kicked me ass?
2- it that ok that i agreed to train with her even tho she is young?
