yeah, i think Jeremy has the right idea. It's probably your soap and or and aftershave your using or your technique(pressure). I have sensitive skin but i don't really expose any open flesh wounds when shaving (pimples etc.). more than likely your reacting to the soap/additives in your setup or your pores are becoming blocked and or retaining foreign debris which could be causing your razor burn/possible infection. maybe check out the post shave treatment forum To use or Not to Use it may be helpful? and for sure let any sores or redness heal before shaving again.
