For a true cocksucker, his mouth is an extension of the cock he's worshiping. The cock and the mouth are two parts of a perfect male sex organ, each incomplete without the other. Connecting mouth and cock is the essential step, a basic fact of life for a man---like breathing and eating, a man has to suck or be sucked. It's a basic necessity, a male human right. And because it's a necessity, it's political. Hence SUCK DICK / SAVE THE WORLD.
