I had the same problem, and electric razors always irritated me LESS, but still caused problems.
Of course I'd go over the same spots over and over and over in an obsessive compulsion to get RID of the hair, not just shave it, so... that didn't help

I tried the Norelco kinds for awhile, but always came back to the regular foil shavers. One trick I liked was using a good coating of moisturizer first... the razor seemed to grip the skin better or something.
I eventually gave up and used an epilator. Works great, but it hurts unbelievably, and can leave ingrowns.
