I shave everywhere except my back, which I cannot reach myself. My wife used to do it before we separated. Now I just get it waxed for contests and live with it otherwise. I shave a different body part each day or so just so it doesn't take so long in one sitting. Repeated weekly. Just got into the habit after my first contest and liked it so I stuck with it.
Everything. But if you do everything you better keep up with it. Otherwise you will be contributing to global warming when you do decide to shave/wax that RAIN FOREST you call hair
What do you guys do for razor burn? I used to be a swimmer and when I shaved for meets I got terrible razor burn on my legs and lower stomach. And I'm not even that hairy. Maybe it was all the chlorine drying out my skin...
Maybe I'll shave my arms, chest, and stomach and buzz cut the rest.
