Even in their adult forms, the two organs have much in common. The clitoris, like the penis, ends in a sensitive, nerve-dense, pleasure-yielding bulb of tissue called a glans. Like the penis, the clitoris has a shaft, and that shaft contains a pair of expandable chambers called corpora cavernosa. It also has a prepuce, or foreskin, just like the penis does, and if you draw it back you may, just as with the penis, discover a wee cache of smegma.
