is longer than my left. has any other people noticed this about their throwing arm?

Your dominant arm is usually stronger.

Sorry haha I read that wrong. I though it said stronger. Nobody's body is perfectly symmetrical according to doctors. If you check your feet one is probably slightly bigger than the other.

TP, If that's true,I wonder if my dad tied my left arm behind my back, cause my left arm has always been stronger than my right.I always suspected I shoulda been a lefty.All these years pitching w/ the wrong arm, oh and thinking out of the wrong side of my brain too!

How much longer is it?

it is about 1-2 inches longer
