Like everything else in life, learning is an experience that you must go through. Hey, I've had a grand total of 11 shaves with my straight. I have had my ups and downs, and some pretty significant cuts along the way. This morning I branched out from just the sideburns, sides of my face and cheeks to get to my jawline and neck area. And not one nick today!!
Take it in stride. Work on small areas first to learn how to manipulate your hands and blade angles.
