Recently, Dr. Ju Young Lee built upon the research of Dr. Helen O'Connell and created a complete 3D mapping of the nerves of the clitoris. What they found was extraordinary. 

There are several complex tree-like branching nerves that innervate the mons pubis, clitoral hood, and skin folds of the vulva. And that's in addition to the 10,000 nerve endings on your clitoral glans.

Here we see the 3D rendering of the internal clitoris. The green and pink areas - the corpus cavernosum and corpus spongiosum - are the erectile tissue, the areas that fill up with blood when stimulated by touch or vibration (note that we have as much erectile tissue as a penis but it's inside the body). 

The blue area - the venous network - is the vascular system - the veins, that carry the blood to the green and pink areas (the erectile tissue). Note the shape of the internal clitoris and how the wishbone shape cascades down on both sides of the vaginal opening.

The blue, red, pink, green, and yellow areas are distinct branches of the dorsal nerve that innervate different areas of the clitoral glans. If you look at section A, you see the complex nature of each nerve branch. Nothing peeters out; in fact, the nerve branches out and reaches more area.

This is my favorite part of the research. These orange strands cascading down past each side of your internal clitoris (the legs and bulbs of the clitoris) innervate your inner and outer labia. They start above the clitoral glans and extend down on either side of the vaginal opening.
