I am a hairy guy. I never had hair on my back, shoulders, just the usual places. (Thank God, whew...) But I shave all the time, and believe the only hair I need is on my head. My girl hates the hair, as so do I. It is just a pain in the ass, and tends to promote more sweat build up, and hair captures unwanted body odor, hence hygene is always a pain with it. I feel cleaner with it removed. Skin feels better aslo.
