These guys nailed it in regards to your questions. Stubear is right on in regards to how to take care of your SR, I do the same he does. I have one recommendation for you to try that works for me. I shave shave pretty much every day and if I use the three pass method you are, my face would be tender as well. I just shave WTG & ATG, then check for any areas needing touchups. Any touchups are ATG. Keep it up!
