Full network of clitoral nerves mapped out for first time

Anatomy of one of least studied human organs could improve outcomes for women who have pelvic surgery

Dumb question, why do “sensitive” spots on the body need more nerves? Couldn’t you just have the normal touch-sensing nerves and map signals from specific spots on the body to stronger/pleasurable qualia in the brain?

Fingers, for instance, not only have higher sensitivity, but also much higher spatial resolution due to the more dense nerve network.

I can't tell why other areas may have needed higher spatial resolution; maybe it was evolutionary important in the past, and remains today. Or maybe just adding more nerves due to a random mutation correlated with better reproductive outcomes due to a stronger signal, or higher sensitivity, so more nerves are present for no other reason.
