Deep-throating

Deep-throating is a sexual act in which a sexual partner takes their partner's entire erect penis deep into the sex partner's mouth, past the epiglottis and into the throat. The practice is a type of fellatio, a form of oral sex. For deep-throating, the penis has to be long enough so that it can reach the back of the partner's throat. The person whose penis is inserted is usually referred as the receiving partner, and the person who performs deep-throating is referred to as the giving partner.
