Yes, many STIs can be transmitted through unprotected oral sex. Chalmydia & Gonorrhea can infect the throat, causing a sore throat. HPV has been linked to mouth and throat cancer when the virus is transmitted via oral sex. Herpes Type II (genital herpes) can be transmitted to the mouth, leading to cold sores on the outside of the mouth. Herpes Type I (oral herpes) can also cross-transmit, causing cold sore outbreaks on the genitals. Since there is a great risk for transmission it’s very important for you and a partner to get tested for any STIs. Until you’ve ruled out infection, always use a condom or a dental dam every time you engage in oral sex.
