Oral sex and canker sore

Question: 

Hello! I performed oral sex with someone and he pulled out right before he ejaculated, but two globs of semen did manage to shoot onto my lips and enter my mouth, which was partially open at the time. I also have a canker sore on the inside of my mouth. I tried to spit the ejaculate out, as best I could, but we were on the beach and it took a while until I was able to find running water to rinse my mouth more thoroughly. Should I be concerned and get tested? His HIV status is unknown.

Answer: 

Hi there, and thanks a lot for contacting the AIDS Vancouver Helpline for you HIV/AIDS related health information.

It sounds like you are concerned about your risk of HIV transmission.

Giving oral sex is considered a Low Risk activity. This means that it can present a potential for HIV transmission because it can involve an exchange of body fluids. There have been a few reports of infection attributed to these activities (usually under certain identifiable conditions). Here are some of the reasons why:

  • HIV needs a human host to survive. Once HIV is outside of the body and exposed to oxygen it can no longer transmit. This mans that the semen that your felt on your lips and in your mouth was outside of the body, exposed to oxygen and thus could not transit HIV to you.

  • Saliva has an enzyme that inhibits the transmission of HIV.

  • HIV needs direct access to your bloodstream in order to transmit. There was no direct access to your bloodstream. Superficial cuts, such as the canker sore in your mouth, simply do not provide the conditions necessary for transmission to occur. For superficial cuts to potential provide direct access to the bloodstream, they would have to be actively bleeding and in need of stitches or surgery to repair. From what I understand, this was not the case in your situation.

Here at AIDS Vancouver we encourage everyone to make HIV testing a part of their regular health care maintenance routine. The only way to know your status is to be tested. If you choose to best tested after reading the information above, you can visit your health care provider you can ask for an HIV test.
