One handed jelqing can be harmful

I don’t know why, but always when I perform jelq with two hands, my dick stays a little pain full in one of the sides, because of that, I jelq only with my left hand, the stroke, strength, ever thing is better with this hand! But I have fear of making my little buddy left. I stay jelqing with only the left, on It’s better I jelq with the two?

Just jelq straight out. Nothing to worry about. Besides I don’t think jelqing wit you left hand exclusively will make your dick bend left.
