Ambidextrous, using a mouse to internet porn meant having to learn how to wank left handed. now equally proficient with both. win!

All my life I was a right hand guy. Then six years ago I broke my wrist and learned how to do left hand wanks. Now it's both and it's heaven. Not where I aim, but when I cum a lot I shoot to my right over my arm and hit the damn wall much of the time.

predominantly my right hand but when I edge I use my left to avoid cumming. So damned awkward I lose my concentration and don't get it back till I switch back to my right.

Right but left comes in useful if the other is busy doing something else. My left hand feels more like someone else's and I very very rarely have an orgasm when using my left hand. As I am usually sitting down on a chair, my spunk gets caught on or in whatever I have available.

I am left-handed but have trained my right hand for masturbation, easier to maneuver. Most times, I have stroked with both hands for comfort.
