I only shave my chest/stomach/armpit hair for occasion, like for holiday or if I was going to a party. You know throwing yo' hands in the air, you don't want any hairs hanging out. Not sure what to do about my back since I can't reach it. Pubic hairs? Nope. It's like a -blam!-ing tropical rainforest down there, with it's own climate and environment. I am one hairy bastard.
