Fixation

one hundred years of solitude is in a ways similiar to a wild sheep chase. In sheep chase boku fixated on the whales penis just before he was going to have sex. In one hundred years of solitude, pillar fixates on what man she is goign to be with by the size of his penis. She chooses the oldest of the arcadia brothers.

While boku fixated on the whales penis i believe as a sign of envy, pillar focused on the size of the arcadia brothers penis as a sign of power. In the machismo code, the bigger the penis, the stronger and more powerful the man is. If she controlled the penis, then she would control the man and therefore have the power.
