Anilingus

[8] Safer sex practices generally revolve around hygiene so as to prevent fecal–oral route transmission of diseases.

[9][10] The term anilingus comes from the Latin words anus and -lingus, from lingere, meaning "to lick"[11] and is based on the pattern of cunnilingus.

[12] It entered English through the 1899 F. J. Rebman translation of Edition 10 of sexologist Richard von Krafft-Ebing's 1886 book Psychopathia sexualis.

If the receiving partner has wounds or open sores on the genitals, or if the giving partner has wounds or open sores on or in the mouth, or bleeding gums, this poses an increased risk of sexually transmitted infections.

Brushing the teeth, flossing, undergoing dental work, and eating crunchy foods (such as potato chips) relatively soon before or after performing anilingus also increases the risk of transmission, because all of these activities can cause small scratches on the inside of the lips, cheeks, and palate.
