X2 on everything TC recommended. Judging by your pictures a couple things come to mind. First of all, and I mean no disrespect, you appear to be a young man so your skin will be more tender than us old guys. If you are shaving with the straight more than say two times a week try straight shaving a little less often and give your skin time to heal. I've been straight shaving for 45 years and my hide is tough enough to shave every day. You will get there too, just give it time. Last thing is your picture of shaving the chin. When you go around the bulb of your chin try clenching your lower lip between your teeth to stretch the skin. Hope this helps.
