Cunnilingus is the act of performing oral sex, using the mouth, lips, and tongue to stimulate the female genitals. The clitoris is particularly noted for stimulation as it is the most sensitive part of the female genitalia. The term comes from an alternative Latin word for the vulva (cunnus) and from the Latin word for tongue (lingua). Most women achieve orgasm easily from clitoral stimulation as part of cunnilingus.
