The clitoris

According to the Kinsey Institute Sexuality Information Service for Students at the University of Indiana

the only function of the clitoris is sexual pleasure.

Do we know of any other element of the body that has no anatomical or physiological function? That is, the clitoris is not necessary for any life process. (In that sense it is like the appendix—although there is some thought that the appendix does serve some detoxification purpose.) Apparently the only reason for the clitoris to exist is so that women will enjoy sex. Its biological function is to encourage women to have sex. I wonder what the Intelligent Design people think about that.
