Optimum functioning of our various sphincters is easier to obtain when we understand how to better accommodate our thoughts to the needs of our bottoms. I often say that our bottom parts function best when our top part—our mind—is either grateful or amused at the antics or activities of our bottoms. It is amazing how much better our bottoms work when we think of them with humor and affection rather than with terror, revulsion, or, worst of all, look away from them in shame.
