may also be used, and another safe sex practice is to avoid unprotected sex which involves fellatio after anal intercourse. 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.
