Never fought seriously. Just alot of friendly fights, and usually I use cowardish wrist-braking techniques
. Works very well, as long as the opponent isn't too serious into the "fight'.
If things are looking scary, it might be a tip to explain to your opponent that you usually go for the balls. That you usually get beaten up, but at least you'll get take a testicle down with ya
. That will keep them of your back
It takes a lot for me to get provoked, and I hope I'll never have to fight someone. I know that I might loose control if I get into a too serious a fight. As a kid I was easily enraged and little would calm me down ...
