I had unprotected oral sex on my penis with a CSW. she sucked my penis. After 13 hours post exposure i went to the Clinic and i was given PEP. The following day i looked for the CSW and took her for the following HIV and STD screening and the results were as follows:

1. HIV I/II determine antibody test-Non reactive
2. HIV I/II (duo) Serum test- Non reactive
3. Symphilis- Non reactive
4. HBsAg-Negative
5.AntiHCV (rapid)- Non reactive

We will be going for gonorrhea and Chlamydia test soon.

Am i at Risk of contracting HIV from receiving unprotected oral sex on my penis? Should i continue with PEP or since the HIV results came back negative and since it was oral sex i received should i stop PEP treatment? Am on day four of PEP treatment.



Thank you for your inquiry. From what we gather from the question, you were asking about the risk of acquiring HIV from receiving oral sex from a woman. From the information given, this scenario is determined to be of Negligible Risk. (There are no evidence or no documented cases of transmission. However, there is a theoretical possibility of transmission under certain extenuating circumstances).

Only certain bodily fluids, such as - blood, semen (cum), pre-seminal fluid (pre-cum), rectal fluids, vaginal fluids, and breast milk carry significant viral loads from a person who has HIV. These fluids must come in contact with a mucous membrane (mouth, vagina, penis, anus) or damaged tissue or be directly injected into the bloodstream (from a needle or syringe) for transmission to occur.

Here at AIDS Vancouver we do not assess the individuals involved, but rather the activities that are being engaged in. Although 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). Using a barrier like a condom or dental dam during oral sex can further reduce the risk of transmitting HIV, other STDs.

It is also important to continue treatment as prescribed, therefore, PEP should be continued for the full duration of therapy.

Recommendation: There is no evidence or no documented cases of transmission. Please remain adherent to your PEP treatment and take it to completion. Refer to a healthcare professional for more personalized answers.

All the best,

AIDS Vancouver Helpline, Jason
