Way too much thought is being put into this shaving thing. I've been doing it for 7-8 years. Actually, I shave my arms, legs, chest, and I get my wife to shave my back. I hate having all of that hair on my body. Most of the really fit guys you see, whether it be MMA, professional wrestlers, what the hell ever sport they're in, they are shaven all over. You don't see too many fit guys looking like a sasquatch. I just use a cheap Gillette disposable razor while I'm in the shower. I cut myself every once in a while but not much. It ain't nuclear physics. Do whatever makes you happy and to hell with what anybody else thinks.
