Adam's actual rib

To feel round the side of one's torso, where the ribs progressively shorten like organ pipes beneath the skin. There is an incompletion to the feel of it, a sense that the boyd is missing something ... those shorter ribs feel, somehow, broken off. Hence, presumably, things like the myth of Adam's rib being removed to make another person. But what puzzles me is that nobody has theorised the psychosymbolism of lack of the rib ... it's all phallus (isn't there anything phallic about these stubby, bone-hard protrusions inside my torso?). Surely the rib cage feels more palpably incomplete than the genitalia of either sex!
