STD, HPV, and oral cancer risk
Chlamydia, human papillomavirus (HPV), gonorrhea, herpes, hepatitis (multiple strains), and other sexually transmitted diseases (STDs) — including HIV — can be transmitted through oral sex. Any kind of direct contact with body fluids of a person infected with HIV (the virus that causes AIDS) poses a risk of infection. Nevertheless, the risk from most of these types of infection is generally considered far lower than that associated with vaginal or anal sex. If the receiving partner has wounds or open sores on her genitals, or if the giving partner has wounds or open sores on or in their mouth, or bleeding gums, this poses an increased risk of STD transmission.
