I won't say I haven't tried shaving various body parts--and at one time there was some enjoyment to shaving the unmentionable regions--but now I leave all body hair alone and only trim the nether regions reasonably. (I only grow a very tiny tuft of blonde, soft hair on the small of my back and I leave that alone too. YES! BACK HAIR! Get over it. I've actually found some back hair to be very attractive on a guy before--but there is gross back hair too. It really just depends. Anyway, I might shave if the hair like on my chest was also on my back, but I guess I have lucky genes so far. Anyway, I digress. Point is, I don't shave.)
Hair is natural, and hairy is sexy.
I actually find a man unattractive if he has no chest hair (with the possible exception of a huge bodybuilder, but then again, he'd be hotter with hair), unappealing and non-sexual if he has no pubic hair (it's too close to emulation of a prepubescent state to me), and it's grotesque to see a man with no leg hair, underarm hair, or forearm hair (as in--wtf, why would you do that? about as attractive as someone with no eyebrows).
Body hair is a secondary sexual characteristic, and as masculinity and a sexualized state are attractive to me, it is therefore attractive. I don't mind people who shave their backs or shoulders or trim their pubes and keep everything in check if their genetics can cause undesired thickness of hair growth, but men who shave completely, to me, are feminizing their bodies. I don't get how this is desirable.
