I used to get awful razor burn from Mach 3's. I stopped shaving all together; for about three or four years I used only clippers (the kind you'd use to buzz your hair). Then, one day, I had a date and wanted to be clean shaven. I pulled out a cartridge razor and, with much effort, got smooth. But, for days to follow, I had those little white bumps all over. I got on the internet and started looking for alternate ways to shave. Straight users here and on other sights claimed that shaving properly with a straight would eliminate razor burn and those white bumps. So I gave it a shot...
