In fact, providing its owner with sexual pleasure is the organ's only known function, and the clitoris is the only organ in either sex with pleasure as its sole function. It has nothing to do with getting pregnant, with menstruation, or with urination.
When a woman becomes sexually aroused, both the glans and the shaft fill with blood and increase in size. The glans can double in diameter. There is no evidence that a larger clitoris means more intense sexual arousal.
