The internal clitoris is the portion of the sensitive female sex organ that extends beyond the tiny, button-like external, or glans, clitoris. The internal clitoris is 4 inches long, on average, and forks out along the sides of the vaginal opening toward the perineum. Only the tip, or the glans, of the clitoris shows externally. That portion of the clitoris can be easily stimulated. However, the internal clitoris may also be stimulated using a powerful vibrator.
More About Internal Clitoris
The glans of the clitoris, or the portion we can see, is connected to the shaft of the internal clitoris, which is made of erectile tissue, just like the penis. When erect, the shaft wraps around the vagina, tightening the vaginal canal. These two legs, or crura, extend down toward the spine, resembling a wishbone. Many people are able to increase their pleasure by stimulating the inner - as well as outer - structures of the clitoris.
