I had an encounter with a female sex worker in which she gave me oral sex with a condom. We did not change condoms when having vaginal sex. I did not ejaculate and stopped in the middle when common sense finally kicked in. Is this high risk behaviour for catching HIV and should I be considering going on PEP?

Hi, and thanks for your question

The risk of HIV transmission to the male partner from the type of encounter you have described is extremely low. We would not recommend HIV Post-Exposure Prophylaxis (PEP) in this instance. In addition to the encounter being considered extremely low risk, the risk of potential side effects and harm from the PEP medication would far outweigh any potential benefit you might glean from it.

If you are interested in learning more about HIV and its transmission, you might find our HIV and AIDS information page helpful. In addition, our Know Your Chances charts give a quick breakdown of high risk and low risk transmission depending on the type of sex and the infection in question. And remember, we always recommend routine STI testing (HIV, syphilis, chlamydia, and gonorrhea) for all sexually active adults.

Let us know if this does not answer your question or if you have any more questions or concerns.
