Every Jiu-Jitsu guy I know has a pretty hot looking wife or girl friend or 2 girl friends. I hope if i train long enough I will get one of those. I heard it comes when you win a tournament or get a purple belt.
Other then that you have to wait till your a BB and just steal one of your student's gf...
Is your focus on competing? Keeping in shape? Having fun? Self defense?
all of these
