There is little sex transmit disease no risk of getting or transmitting HIV from oral sex. Other STDs and hepatitis can be transmitted during oral sex.
Latex barriers and medicines to prevent and treat HIV can further reduce the very low risk of getting HIV from oral sex. Risk of HIV The chance an HIV-negative person will get HIV from oral sex with an HIV-positive partner is extremely low. However, it is hard to know the exact risk because a lot of people who have oral sex also have anal or vaginal sex. The type of oral sex that may be the riskiest is mouth-to-penis oral sex. But the risk is still very low, and much lower than with anal or vaginal sex. Risk of Other Infections Other STDs, such as syphilis, herpes, gonorrhea and chlamydia, can be transmitted during oral sex.
Anilingus can also transmit hepatitis A and B, intestinal parasites like Giardia, and bacteria like E. Reducing the Risk Individuals can further reduce the already low risk of HIV transmission from oral sex by keeping their male partners from ejaculating in their mouth. This could be done by removing the mouth from the penis before ejaculation, or by using a condom. Using a barrier like a condom or dental dam during oral sex can further reduce the risk of transmitting HIV, other STDs, and hepatitis. A dental dam is a thin, square piece of latex or silicone that is placed over the vagina or anus during oral sex.
