you just get better at it the more you do it. one good thing to have though, is one of those little tiny trimmers you can get at some drugstores for trimming bikini lines and tyhose types of places. they trim really short in case you miss an area. also i would suggest a vibrating mach 3 or fuson. they sound like a gimmick, but really work. i get irritation without one, and almost never get it with one.
