(Latin: connus: con (female sex) + lingere: to lick) The act involves using the tongue or licking the female genitals. It is also called "cunnilingus", "clitorilingus", "oragenitilism" and irrumation. Regardless of the name, it has been around since the dawn of time. This practice is not limited to humans since animals also lick each other. According to a 1993 report from Spira, 79% of people responded to having practiced cunninlinctus.
