Cunnilingus is oral sex for a woman's pleasure. Contact with the mouth and the yoni (Sanskrit for the female genitals) including the vulva (external labia—the folds of tissue at the vaginal opening) and the vaginal canal (inside of the yoni) using lips and tongue can bring great pleasure and arousal to most women. For many women it is through cunnilingus that they are most easily orgasmic.

Also, most men love to have their faces at the yoni for several reasons. One, female pheromones called Copulins (chemical sexual attractants) are produced by women primarily at the yoni. These Copulins are registered in the male nose. Second, one of the biggest turn-ons for a man is how turned on and how pleased his lady is. Third, most male lovers rather enjoy the sensations of licking and sucking at the yoni, in other words this practice typically gives men great pleasure through all five senses (taste, smell, see, touch, and hear).

A fully sexually aroused woman’s genitals taste, smell, look, and feel amazingly wonderful, and the sounds she makes while you are pleasing her can drive a man to orgasm by itself alone.

So, while it is not required, no man could be considered a great lover without skill in performing cunnilingus.
