I shave everything except my arms (and my head obviously xD). I dislike body hair, so I shave it, and I look way much better than with hair. Plus, where I'm from most of young guys shave, it's rare to see a 20 y/o guy with body hair.
I don't see why guys complain about shaving. I don't have to shave, to be honest. I'm naturally hairless. I do, however, trim it up downstairs. Can't stand an lot of hair, but no hair at all looks weird. So I trim.
Even if I did grow a lot of hair, I'd shave. I don't like a lot of body hair on me, so I'll get rid of it. Think it just looks weird.
I shave my armpits and pubs, for the rest of body I use a trimmer to trim my chest and legs also see no reason to trim my arms and I'm naturally hair free on my back. For my face I use wax for forehead and ears and about beard I grow stubble.
