Abstract

The human penis is usually seen, by anatomists, as a patchwork of tissues with distinct and separate functions. Each function makes intuitive good sense; for instance, its skin covering facilitates sliding movement. The glans is seen as touch-sensitive and, therefore, an important source of erogenous sensation, which Guyton, in his standard book on human physiology, informs us is the main trigger of sexual reflexes. The frenulum, like the glans, is thought to have touch-sensory functions; at the same time it helps retain the foreskin on the supposedly sensitive glans. Corpus spongiosum surrounds and supports the long male urethra and may facilitate ejaculation. The question is whether this is the only function of the longest part of the penis, which forms the bulb of the penis at one end and glans at the other. From all this, it is reasonable to suppose that the penis is structured to physically support the glans and its function, namely, the generation of touch and then erogenous sensation which, in turn, is thought to be the main trigger of sexual reflexes including erection and ejaculation. Maybe so, maybe not.
