Can I get an STI from oral sex?
Yes, STIs can be transmitted during unprotected oral sex. Oral sex is a much lower risk activity than intercourse, but there's still a possibility for transmission. Not using a condom, dental dam, or other barrier puts both partners at risk. This means that performing and receiving oral sex puts you at risk. Some STIs are more likely to be transmitted during oral sex than others, including:

Herpes is transmitted by skin-to-skin contact with a developing or existing sore. The virus can be transmitted from genitals to mouth if the person giving oral sex has or is developing a cold sore. It can also be transmitted from mouth to genitals if the person receiving oral sex has or is developing a genital sore.

Gonorrhea is transmitted when bacteria are present in body fluids. A person giving oral sex can get a gonorrhea infection of the throat if their partner has gonorrhea.

For the person receiving oral sex, there's little chance of contracting HIV, although it's difficult to pinpoint when HIV has been transmitted because people rarely engage in only one type of sexual activity. In the case of fellatio (oral sex on a man), the HIV virus theoretically could gain entry from the mouth to the opening on the tip of the *****, or through an open cut or lesion on the *****. If you receive oral sex, however, you mainly expose yourself to saliva, which has negligible concentrations of HIV.
