Right-handed. Although I'm usually good with my hands (I play guitar, piano, and drums) I just cannot wank with my left hand.

Mostly right, but either.
I'm right handed, jerk off right handed, and mouse with my left hand.
Right handed and primarily stroke with the right. That left hand though gets some practice - always nice to have some "strange" working my cock over now and then. It's a totally different experience!
Right handed, and use right mainly. But some times I use my left to switch things up.
I'm mostly left handed, but sometimes use my right.
Old but still jacks and cums
Seems about 50/50, strange you would have thought more right handers really?
Cock in hand, ready to wank!
I alternate based on the feeling and fantasy
Master Stroker
I am right handed but almost always jackoff with my left hand. I can hit that sweet stop on the underside of my cock much better with my left hand.
Be happy, suck a cock
I'm left handed, but jack off with my right hand the most. I concentrate jacking right up around the corona of the head and just below. Sometimes I use my left hand, and I seem to hit the edge of the head just a little different that will get me to cum every time.
im right handed but sometimes jerk off with the left hand..for a different feel..if im on the computer I use my right hand for the mouse and key board and left for cock playing and stroking..you can say im a switch hitter...
love to cum alot
Right handed and 99% use the right. When I'm looking for some "strange" I'll go left - and love to use the fleshlight!
Always right handed, but surgery to my hand forced me to use left hand. Now I can use either. Left hand actually feels different/better
Left, definitely
