In oral sex, irrumatio is performed by actively thrusting the penis into the mouth of the partner. In slang, this act is called face fucking, throat fucking and skull fucking.
As with fellatio, it may be performed to induce male orgasm and ejaculation of semen. The passive partner may simultaneously be induced to climax if so desired. It can also be used as foreplay prior to vaginal or anal forms of intercourse.
One method for the passive partner to overcome such difficulties is using the so-called stopper technique by wrapping one hand around the lower shaft of the penis thus being able to control its movement. Irrumatio can take place in a variety of positions.
Possible positions:
The passive partner with the back on the bed with the head tilted over the edge or the passive partner kneeling in front of the active partner.
Fellatio and irrumatio can be used interchangeably during oral sex. Indeed the distinction between fellatio and irrumatio has vanished in modern English and the latter term has fallen out of widespread use.
According to Maggie Paley's argument in her work, The Book of the Penis, some receivers regard receiving oral sex as an ego boost, believing that such an act is a form of dominance over their sexual partner because of the overt submissive nature of the act; the giver may often be on their knees before the receiver to perform the act of pleasure.
As the Roman conception of the act also indicates, this is more so for irrumatio than fellatio in oral sex, as the male partner is dominant in action and the act of deep throating is easier.
