Leading Biologist Uses Evolution to Explain Why Cum Tastes So Nasty

Jerry A. Coyne, Ph. D, begins his hypothesis with the question, “Why does semen taste so foul?” Clearly Dr. Coyne would have never arrived to that question if he’d just try one of our famous Spunky Candied Pecans. In a theory he calls the adaptive significance of semen flavor, Dr. Coyne writes:

One answer, of course, is that the chemicals necessary to make an ejaculate effective have the side effect of tasting bad…But this proximate answer will not satisfy the diligent evolutionary psychologist. After all, natural selection could presumably add some sugars or good-tasting stuff to semen if it were advantageous to do so. Why does it not do so? A moment’s reflection gives the answer.

Natural selection maintains the repugnant taste of semen so that a man’s sperm will wind up in the appropriate place: the vagina and not the stomach. So long as sperm tastes bad, women will not be tempted to swallow it, but will turn their male partner towards conventional intercourse, which of course is the only act that will produce children. In other words, any male with good-tasting sperm would have fewer offspring than his competitors. A man whose sperm tasted like honey would probably not have any children at all.

Sure, he wouldn’t have any children, but at least you wouldn’t have to dip his cumsicles in Sweet ‘N Low.
