Given the need for a cleavage to be surrounded by breasts I can understand why, if he had some of his own, BM would never feel the need to leave the house because he would be too busy deriving pleasure from playing with his own.
Personally, if I return to this world as a woman I intend to spend the first fifty years (i) trying to find the mythical "Right Spot" and (ii) trying to understand the connection between sex and headaches.
