I am a male and I had sex with a female prostitute using a condom. I was fairly intoxicated during the time and for some crazy reason I decided to perform oral sex on this woman. It was fairly short lived - probably less than a minute I would estimate, but nevertheless it happen. 

During intercourse, condom was on the entire time and I don't believe there was any condom failure. Of course I immediately washed my mouth and face off with soap and water after everything was done but since the second I woke up the next morning, I have not been able to rest easy at what I could have possibly caught from this woman. I have took 3 HIV RNA tests - (One at 18 days, 31 days, & 42 days since exposure)  -  I have also took 5 fourth gen lab tests (13 days, 23 days, 31 days, 38 days, & 45 days since exposure) 

Along with the fourth gen tests, I took 10 panel STI tests every time.

All tests with the exception of Herpes Type 1 have came back negative. Can I stop testing for both HIV and all the other STIs at this point or do I still have possibility of something popping up? 

NOTE:  About 10 days after the exposure I did have a red rash of some sort on the head of my penis. I went to a urologist who told me it was candida and didn't even want to test me for STDs. He gave me a cream and everything cleared up about 10 days after I started applying the cream. 

Cunnilingus -- oral vaginal contact -- is very safe sex. All STDs are rare in that circumstance, and there has never been a known case of HIV transmission. Most female sex workers don't have HIV, but even if your partner was infected, you were at no risk of HIV. And in any case, your HIV blood tests are proof you were not infected. For the same reason, it isn't surprising your STI tests also were negative:  you were seriously over tested and for sure don't need any more STI or HIV tests.

No STI causes a red rash on the head of the penis, but fungal infections like yeast (candida) often do so. That's why your doctor saw no need for STI testing. 

So all is well. Your penile candida is gone and you do not have HIV or any other STI from the event described. No more tests, please!

I hope this has helped. Let me know if anything isn't clear.

The reason I have been so concerned is because I have received conflicting information both from the internet and the Doctor that I initially visited with when I had my first set of tests at 13 days past exposure. He stated that indeed I was at risk of a variety of STIs & HIV due to my oral contact with the woman's genitals regardless of how long or intensive the oral sex was. And he also stated that HIV tests were not conclusive until 90 days past exposure. At this point is when I started my independent research and found a lot of conflicting info about both the risk of STIs & HIV contraction given the act that I performed. Some say it's impossible to get HIV unless I had actual full blown bleeding gums and some say that a virus could easily get into my bloodstream through a small cut that I wouldn't even know about or even through my throat. But putting all that aside because what's done is done - I figured that my only way of truly knowing would be by testing. So there began both the full panel STI & HIV testing and the HIV RNA testing. Many websites & articles that I read stated that a 4th Gen test was conclusive at 45 days and an RNA test was definitely conclusive at 21 days and beyond. But then there are websites including the CDC that state that HIV tests are not conclusive until 90 days past exposure. Today marks 61 days since my exposure and I actually had took another set of tests on day 58 past exposure when I initially wrote to you. (On day 58 past exposure I had done another full panel STI testing including a 4th Gen HIV and I had also done another HIV RNA test - All through LabCorp) - And all of the results did come back negative. I want to put this all behind me an move on with my life but all of the conflicting info that I am getting is making it hard. So my question to you is this - are my tests indeed conclusive? and secondly - When you say that my performance of oral sex on this woman would not have resulted in my catching HIV or any other STIs for that matter - why are there so many conflicting articles about this and why did the initial doctor at the clinic that I visited 13 days past exposure state that indeed I was in danger and my test results wouldn't be conclusive until 90 days. Again - I apologize if it seems like I am beating the dead horse here but I have never been through anything like this in my life. 

I look forward to hearing back from you.

Thank You for your time.

The internet is not your friend. As you have found, conflicting information is abundant. But the fact remains that there has never been a known case of HIV acquired by cunnilingus. In the 40 years of the known worldwide HIV/AIDs epidemic, with millions of infected people, do you reallly think you might be the first? Get real -- it didn't happen. And in any case, the tests you have had are conclusive. How much proof do you expect, need or want? You also need to pay attention to when the information you need was written. I don't care what you might have found on CDC's website, but it simply is not true that CDC currently states "that HIV tests are not conclusive until 90 days past exposure." That adivce was valid 15 years ago, but not since then.
