STD Testing Accuracy and Risk Assessment

[harj66]

Hi There
Thanks for this great forum!
I will get straight to my questions.  Over the last year (since my 2010 STD check-up) I have had 4 encounters with men that went like this:
- The first man back in September 2010 - We engaged in mutual masturbation, some light kissing and frottage with my clothes ON the entire time... I was never naked.
- The second man was back in March of 2011 - We engaged in some kissing, I stroked his penis and he simulated anal sex on me (however once again I was FULLY CLOTHED at the time... There was no actual sex.
- The third man was back in May of 2011 - We met in a car and did nothing more then mutual masturbation - my concern here being that after touching his own penis that had some precum on it, he then touched mine (I am uncut).  Nothing else happened with this man
- The fourth man was back in June 2011 - This man sucked on my scrotum for about 20 seconds and I did the same to him (I only sucked on his scortum, not his penis at all and he also did NOT suck my penis at all either), afterwards me mutually masturbated each other to completion.
I tested for all STDS on July 22nd which was exactly 6 weeks after my last encounter.  My tests came back negative for HIV, Sphillis, HEP A,B and C as well as oral and penile Gonnorhea and Clamydia (urine test and oral swab).  I am now in a committed relationship with a woman.  We had unprotected sex a week ago and she developed some buring after unprotected sex.  Do you believe that this is just a UTI or could I actually have an STD from the experiences described above that was not picked up through my STD testing?  Please share your thoughts, I am stressed out.
Thank you,
Harj

Hi Doc!!!
Based on the sexual experiences I described in this earlier post and my negative duo-test 6 weeks after my last possible exposure can I fully rule out tye idea that I am hiv positive. I have had no other sexual encounters except with my now long term monogamous partner.
My concern arises because 5 days ago we had unprotected vaginal intercourse and now she has come down with an awful illness - very high fever, sore throat and muscle aches. I am terrified at the thought that I might be positive and have caused her to become so as well. If I need to pay again for this follow up question. I will. Any clarity though would be wonderful.
Thank you so much.
PS - is 5 days too early for ARS Symptoms?

Yes, a DUO test at any time beyond 4 weeks provides totally reliable test results. EWH

Just wanted to tell u that u were 100% correct doc... She only had a uti... Thanks again...
One final final quickie question.... Would u consider a duo hiv test at 6 weeks following any potential exposure to be completely 100% accurate... Have found mixed reviews on the topic
thanks doc

No, while Macrobid might have some activity against STDs, it is not reliable for them, nor is it recommended.  It is pretty specific therapy for UTIs.  

The urine tests for gonorrhea and chlamydia are highly reliable.  Believe you results. EWH

Hi Dr. Hook
Thank you very much for your prompt response. Its much appreciated. I do have 2 final thoughts that I hope you will be able to comment on.
First - my girlfriend was seen by a doctor for the burning sensation while urinating. The doctor prescribed her macrobid. She is on day 3 of the antibiotic and the burning has now essentially disppeared. Is macrobid ever prescribed for stds? If not would u conclude that this was very likely just a UTI?
Second - based on my urine test for gonnorhea and clamydia how accurate is the urine test (in your own practical experience)??
I promise thats it for me in terms of questions.
Thanks again

Welcome to our forum.  The exposures you describe are extraordinarily low risk.  Theoretically a few of the more easily transmitted STDs, like gonorrhea or chlamydia could be transmitted by the transfer of genital secretions during mutual masturbation but the fact is, that in our combined over 60 years of care of patients with and at risk for STDs, neither of us has seen or heard of any person who got an STD in this manner- never.  In your own case, you have gone further to rule out infection and your negative tests serve to confirm what I just said to you- not only were your exposures very low risk but you have proven that you did not get an STD.  Believe your test results.  You are not a risk to your current partner.

I will mention however that UTIs in women can occur following sexual intercourse, thus you may have contributed to your partner's risk for a UTI but you did not give it to her.  

I hope these comments are helpful. Take care. EWH

One last point to consider, during the sex with my girlfriend (which was last week) she used a spermicidal film as a contraceptive - could that have increased her chance of developing a UTI?  
Finally, do you believe any of the experiences described above have put me at risk of developing any STDS - or should I accept my negative results (be confident) I am negative and be confident that my girlfriend has a UTI and not an STD that I gave her???  
Thanks again for your advice.
