3 weeks ago I received unprotected oral from a male sex worker (I’m a male). 

I tested 11 days after the incident and everything was negative (syph, chlam, gon, hiv, hep). I suffer from anxiety and I’m not sure if I need to retest for anything. 

What are the chances of having caught something ? If I caught something it would be obvious ?

I was thinking to retest at the 1 month mark for peace of mind. 

Please advise. My anxiety is driving me to depression and mental anguish. 

I have to worry about HPV ? 

Oral sex is quite low risk, with low chance of all STIs and zero risk for some. The reasons are both that oral/throat STIs are uncommon, so the oral partner rarely has nothing to be passed on; and even when oral infection is present, the chance of transmission is low for any one exposure. The main risks are for gonorrhea, herpes due to HSV1, and nongonococcal urethritis (believed to often be caused by normal oral bacteria). Syphilis is a risk, especially for sex between men, but still quite rare. Your test results are reassuring in regard to gonorrhea, but the syphilis blood test was too soon to mean anything. Chlamydia, HIV and viral hepatitis are no risk at all from such an exposure so those negative test results are expected.

Would infection "be obvious" if you caught somethings. Yes and no:  yes for gonorrhea and NGU, usually yes for syphilis and herpes, and usually no for the others.

HPV is rarely transmitted by oral sex, and assuming you have had an average sex life, you already have been infected (perhaps a few times) and this exposure does not further raise your risk. And the chance is even lower in this situation, i.e. with an HPV vaccinated pattern.

Do you need follow-up testing? Definitely not for gonorrhea and chlamydia. It's optional for syphilis. No need for HIV, but certainly OK to do it (6 weeks after the event) for reassurance. For sure no testing for anything else.

All in all, this was a very low risk event. You really needn't be worried about it.

Mention we had penis to penis contact, not sure if there is something to worry about there?

For retesting , can I do it sooner than the 6 week mark ? And is that just for syph ? 

Can I have unprotected vaginal intercourse with my partner in the meantime ? 

Also what does 11.95 iu/L mean for

The hep B test result ? Does that mean I got the hep B shot when I younger ? I can’t remember all my immunizations 

Syphilis is the only necessary test, although almost everyone in your situation would include an HIV test as well. Negative results for both at 4 weeks would be very reassuring (at least 95% conclusive) but both need 6 weeks for 100% reliability. 

The lab result you give is the numerical value but says nothing about exactly what the test measured. If it's hepatitis B surface antibody (HBsAb or sometimes called anti-HBs), it means either past vaccination or past hep B, cured by the immune system. Either way, you are immune.

The 11.95 value was listed under  the hep b surface antibody section.

I don’t see any sores in my genitalia area. 

Yes I did urine test for gon/chlam. 

Last couple of questions:

-any risk of anal fingering ? That’s what i did as well to the other individual. 

-I constantly check for warts or sores on my genitilia and I don’t see any. If they were to appear how long would it have taken ? 

Sorry for all the questions but it’s my anxiety and worry 

Fingering of any and all body orifices is entirely free of STI risk.

The chance of warts is almost zero, and there's no point in looking for them now. Genital warts do not appear sooner than 6-8 weeks after exposure and it can be up to a year or two. 

That completes the two follow-up exchanges included with each question and so ends this thread. Before I close it, let me know if there are any final brief questions or concerns.

Any further 

 worry is just my mind / anxiety ?

Thanks for the thanks. Take care and stay safe.
