As your body is made up of mostly water (which doesn't compress well under pressure) the only bit that are affected are the air spaces. Your lungs expand and contract fine as the 2nd stage reg keeps the air at the same as ambient pressure - so it doesn't feel any harder to breathe. Your ears have to be equalised as you descend, which is the same as you do in a plane when your ears pop except you do it more frequently. Other than that you don't notice much of a difference at 2ft as you do at 100ft. The main thing you can tell the difference is your wetsuit compressing.
