Obviously you haven't bothered to read, much less subscribe, to the advice others that have gone before us have given; and that is, to try only a portion of the face at first, then add to it as you get better. MOST OF US DIDN'T EITHER!! My advice would be to watch a couple more videos of straight shaving, take a good look at your beard to get a better idea of which direction the hair is growing, wait until you feel your face is up to it(sometimes mine hurt, but by the next day it was fine) either today, or tomorrow, then go for it!
