Irrumatio

As the quotation from Butrica suggests and an article by W. A. Krenkel shows, irrumatio was a distinct sexual practice in ancient Rome.

[9] Oral sex was considered to be an act of defilement: the mouth had a particularly defined role as the organ of oratory, as in Greece, to participate in the central public sphere, where discursive powers were of great importance.

[10] Furthermore, as Amy Richlin has shown in an article in the Journal of the History of Sexuality, it was also accepted as "oral rape", a punitive act against homosexuality.

[12] Catullus threatens two friends who have insulted him with both irrumatio and pedicatio in his Carmen 16, although the use could also mean "go to hell," rather than being a literal threat.

[16][page needed] Peruvian erotic pottery of the Mochica cultures represent a form of fellatio in the vases showing oragenital acts.
