An option I always recommend men consider is trimming. You don't have to choose only between natural versus totally shaved/waxed.
Several companies make electric trimmers just for this purpose (Norelco's Bodygroom for example). Keeps enough of the manly hair, but without the mountain gorilla look. You're probably cutting the hair on your head and any beard you wear, so why not groom excessive hair on the rest of your body?
If you want to trim your back you'll probably need a helper, but that can provide some fun. Never turn down an opportunity to get naked with another guy. In return offer to do his back and ass, too.
