Thank you for all your help. Should I try to get the drugs for PEP after performing oral sex on a sex worker just on the clitoris no penetration. Not sure if she orgasimed or not. That was my only risk since I realized what I was doing and I freaked out and left. The whole thing could have taken anywhere from 5 to 10 minutes Thank you

Post-exposure prophylaxis is an experimental method of preventing HIV infection by starting an antiviral medication regimen within 24-36 hours of exposure. Since the procedure is still not widely practiced, is expensive, and can cause troubling side-effects for people, PEP is only recommended for individuals who have a significant exposure to HIV. Criteria vary, but PEP is generally warranted when someone has unprotected vaginal or anal intercourse with an infected person or a person from a high-risk group, for a victim of sexual assault, and for health care workers who have a significant occupational exposure to a patient.

It is highly unlikely that you would have been infected by the incident you describe, and I'm assuming too much time has elapsed for PEP to be effective anyway. Performing oral sex on a woman rarely causes HIV infection.
