I think I did better with my left hand my first few shaves. My lack of experience doing anything with that hand forced me to be very careful, delicate, and deliberate. I got false confidence with my right very early and paid the price for going "willy nilly". For the record, nothing calms you down like cutting yourself for the first time. It's not a question of IF you are going to, but a question of when. Once you are over the first blood hump, it's all just old hat.
