Deep-throating

Deep throating is a form of oral sex, a type of fellatio in which the whole erect penis is taken into the mouth, (sometimes including the scrotum as well).

Since the average erect penis is longer than the average mouth is deep, this requires suppressing the gag reflex in order to partially swallow the end of the penis.

In order to perform this form of fellatio one must relax all the muscles at the back of one's throat while gradually inserting the erect penis into the throat. It is helpful to have a patient partner. The best technique for practising the technique is for the giver to lay on their back on a bed with their head hanging over the edge. This ensures throat and mouth line up and aids penetration of the penis. Deep throating may facilitate swallowing of the semen, since it bypasses most of the tongue and tastebuds.

Deep throating was featured in the 1972 movie Deep Throat.
