Did you know that the average length of a an erect Silverback gorilla penis is 2 inches? Don't believe me? Go check it out yourself on your friendly neighbourhood gorilla.
Since a clit and a penis start out as the same thing, and only diverge later during gestation, I strongly doubt that there is a difference in the number of nerve endings. But I suspect that the clit is more sensitive, as the number of nerve endings per square cm are much higher. A greater density of nerve endings means more pleasure for a women, unless she is with some jerk that thinks DATY is dirty.
