The clitoris is a little bud to be found at the top of the inner lips, where they come together.
The size varies: it can be small as a pin-head or 10 millimetres in diameter. On average it has the size of a pencil eraser. Size has nothing to do with its sensitivity and sexual response. A small clitoris can be less or more sensitive than a big one.
Latest research shows that the clitoris is much bigger than the little spot we see. It probably has a wishbone-like structure. The legs of the wishbone run beneath each of the lips.
For orgasm the clitoris is indispensable. It’s a girl’s most sensitive spot and its sole purpose is to give pleasure. The sensitivity is comparable to the sensitivity of the tip of the penis of uncircumcised guys.

The disappearing act: why it can be difficult to find the clitoris when a girl is excited.
