Hello doctors. I am a 44 year-old straight white male and only engage in sexual activities with women. A few weeks ago I had oral sex as a one night stand with a woman that I don’t know and I went down on her and she went down on me.  I’ve done this with both civilians, as well as with commercial sex workers in the past. When it comes to penetrative sex, I always wear a condom.  In the encounter from a few weeks ago, I realized after I was performing oral sex on her vagina with my mouth that she was bleeding and I may have ingested some of that Blood. I am not aware of any open sores in my mouth at the time.  My question to you is how likely am I to have potentially have contracted HIV from such an encounter or any STDs if I don’t have any symptoms after a few weeks? Is hep a/b/c possible?  Im vaccinated for hep a and b. I also sometimes lick their assholes.  If you can also explain any of the details of your answer as to why it is or isn’t possible for me to contract something from this , I would really appreciate that.  I tend to worry and overthink these things.  Do I need to get tested for this? Just looking for some peace of mind before I get tested for anything to guage my expectations.   Thank you

Welcome to our Forum. Thank you for your questions.  The exposures you describe are virtually no risk risk. It is unlikely that your partner had HIV or other STIs.   There are no proven cases of HIV acquired from receipt of oral sex, ingestion of genital secretions or blood from an infected person have never been proven to result in HIV infection.  I have never seen or heard of a person acquiring HIV from performing cunnilingus of HIV on an infected person.  Your vaccination status assures you that you are not at risk for hepatitis.---
