I'm a guy and I am right handed. I have always masturbated with my left hand. I just can't masturbate with my right hand, It doesn't feel right for some reason.
This is so funny -- it's the same with ME! I do just about everything right-handed. I punch righty, kick righty, throw righty, snowboard "regular-footed"... but ever since I began doing it, I have masturbated with my left hand! I don't even know how it started out that way. There are only a few things I do left-handed: masturbate, shoot pool, and write. If I do masturbate right-handed, for some reason, it seriously interferes with my ability to conjure up a mental fantasy! Weird, huh? -Jeffrey
I use both, either at the same time, or whichever one is most convienient. I find that I will use the same one for awhile,(like 6 months) and then switch it up for the next 6. It feels quite different to switch it up.
