Oral sex. Giving someone sexual stimulation using the mouth, lips or tongue. People also call oral sex “giving head” or “going down on someone.” Oral sex on the penis is called fellatio—a blowjob—and on the vulva and clitoris, it’s called cunnilingus—eating pussy. Oral sex in the anus is called analingus, or rimming.
