[IPS] Nairobi -- The tips of our fingers have densely packed nerve endings. That is why a miniscule paper cut activates our pain receptors and causes stubborn pain for a day or two. Now consider that a clitoris has over 10,000 nerve endings. It is the human female's most sensitive erogenous zone, explaining the sexual pleasure it elicits at the slightest touch. A paper cut on your clitoris would be agonizing yet does not compare to the pain of female genital mutilation - or FGM.
