Definition: Cunnilingus is the act of performing oral sex using mouth and tongue to stimulate the clitoris and all the female genital area. The term comes from a latin word refering to vulva (cunnus) and the latin word for tongue (lingua).
The clitoris is particularly excitable and usually is the most sensible part of a woman's genitalia. Some women easily reach orgasm when they get their clitris stimulated. This is somenthing you must know and be skilfull at in order to give a good cunnilingus.
The clitoris is a woman's easiest body part to arouse sexually, but sometimes is too sensitive to stimulate directly with a penis, specially in the earliest female excitment phases.
To give a good cunnilingus, you must first start with a smooth stimulation of all the genital and labia area. The tip, blade and underside of the tongue can be used to perform this kind of stimulation, as well as the nose, chin, lips, and (with extra care) teeth. Movements of the tongue can be slow or fast, regular or erratic, firm or soft, depending on her preference and timing. The tongue can be inserted in the vagina, either stiffened or moving. To buzz while performing cunnilingus is specially exciting, tones and rithm's efectiveness may vary depending on the person.
