I prefer a guy to be natural but well groomed. back/ear/nose hair is not sexy adn should be trimmed. I don't like guys who shave their chest because it only leads to stubble. Waxing is fine if that's what floats your boat, but I'm also not much of a fan of ingrown hairs and red spots all over.
Keep your chest, arm and leg hair, but just maintain a degree of grooming with it.
