The metabolic symbolism of mutual exchange between body and world is paramount.  The object of hunger, the food to be 'taken in,' is the world itself; while the other, productive side of the process is symbolized by 'output,' that is, evacuation.  The dominant symbol is not the semen; in creation mythology, urine, dung spit, sweat, and breath (and later, words) are all elementary symbols of the creative principle.
