Used to use my right all the time but now since I jack a lot while using my pc, I use my left hand.
So it's either left hand or both at the same time.

left...sometimes i switch it off though.

right, but a few rubs with the left feels like someone else is touching you

primary left so I can type with right..kind of..like amny others when I started using my left it felt like a new friend
was lending a hand. Now for long term and edging I always use
my left even when not at the puter...

using left now...

i used be a righty before i got my computer. now i'm a lefty

Ambidextrous so either (or both). One at tip/shaft, another balls and sometimes asshole.

i use my left when im at my computer chatting or looking at porn, but my right for those absolutely necessary quick jacks before bed.

i use my left hand to jack with. tried using my right hand but it didnt feel the same.

anyone in right now? the chat wont work for me...This way is slower, but I'll take anything I can get....!

if im jerkin off at the computer like i am right now i use my left so i can type and use the mouse with my clean right hand. some nights i get really slutty and just dont care. but i can jerk off with both fists. they feel different but both good

Righty, when Im ready to EXPLODE, lefty when I'm surfing the net!

Same for me... I switch off especially if I'm edging for a while.

Onan

I've always jerked off with my left even though I'm right handed... I'm pretty sure its because the mouse is on the right side of the keyboard

Right handed here but jackoff with left usually

Right hander here
