Many people find oral sex an intensely pleasurable experience. People use different terms to refer to oral sex including formal terms like fellatio and cunnilingus and slang terms like blow jobs and giving head. Usually oral sex means one person kissing, licking or sucking another person's genitals. Doctors and researchers can't be sure how many people have acquired HIV through oral sex. In late , researchers looked at all the available evidence and calculated that the risk of acquiring HIV from oral sex was very low, but that it wasn't zero. It is clear that oral sex involves much less risk than anal or vaginal sex. HIV is most easily passed on during anal sex, vaginal sex, sharing injecting equipment, and from mother to baby.

The chances of HIV being passed from one person to another depend on the type of contact. HIV is most easily spread or transmitted through unprotected anal sex, unprotected vaginal sex, and sharing injection drug equipment. Unprotected sex means sex in which no condoms or other barriers are used. Recent research has shown that people living with HIV who take HIV drugs and whose viral load is undetectable too low to be found with standard tests cannot pass the virus on to their sexual partners even during unprotected sex. That said, unprotected sex puts you at risk for other sexually transmitted infections. Oral sex involves contact between the mouth and the genitals.

Oral sex involves using the mouth to stimulate the penis fellatio , vagina cunnilingus , or anus anilingus. 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. Though the risk of HIV transmission through oral sex is low, several factors may increase that risk, including sores in the mouth or vagina or on the penis, bleeding gums, oral contact with menstrual blood, and the presence of other sexually transmitted diseases STDs. 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. 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.
