Autocunnilingus is a form of masturbation involving the oral stimulation of one's own vulva. Performing cunnilingus on oneself requires an unusually high degree of flexibility such as that of contortionists or double-jointed people.
While possible for a small number of women, autocunnilingus has not been thoroughly studied or well-documented. It has, however, been reported as a self-destructive fantasy, and occurrences of the act have been reported in macaques and chimpanzees.
In "Besorgung", one of his , Goethe imagined Bettina becoming sufficiently limber to perform autocunnilingus and do without men. Camille Paglia compares the resulting image to William Blake's "engravings of solipsistically contorted figures".
