Try "Chi Na"- if you can find a teacher.
You could learn massage therapy that teaches a lot of pressure points. Learm some Aikido along with it- go from one class to the next and question your Sensai about what you are learning in the massage course. Kinda round about way to learn it, but it would probably work <shrug>.
Try to keep in mind taht martial arts is not about fighting, its about life leasons, and not using what you know to hurt people. Concentrate on learning about life a nd you will have to fight very seldom.
I know of a 4th dan black belt that took a punch to the face (sucker punched). He looked at the guy and told him- "man, that was a good hit. You beat me; I lose," surrendering. The guy who threw the punch came again- laughing, Mr Karate parried, retreating, blocking and avoiding- "you won, dude, let it be."
He submitted the guy, tried to talk to him to calm him down so that he would not have to call the cops, but punch guy would not mellow. The police were called and the puncher was arrested. At the trial on the stand the 4th dan was asked why he didn't hit the guy- "it wasn't me, he was mad at, it was himself, I just happened to be there."
Understanding people is what martial arts is about, knowing yourself and understanding that fighting is not always the way.
