STD chances...syphilis/hiv

[anxiety007]

Here is my situation...I am male, from midwest, 37 days (5 weeks and 2 days)ago I received oral sex (2mins no ejaculation) from female of marginal background,  I was tested for Cham/Gono and was negative....but as many on this forum my anxiety and guilt is getting the best of me....so I focus on the others, like syphilis/HIV.......I have no symptoms(no chancres) and understand that a conclusive test can be taken at 6 weeks so I am in a waiting game...and I have read that on average symptoms occur at 21 days for syphilis....

so my questions are...

Would I definitely see the chancre if I had one?

since I have not seen symptoms at 35 days can I feel ok that I do not have a std(syphilis)?

Would you recommend testing?

Can I have sex with my female partner without fear of transmitting anything to her?

Thanks in advance...

Doctor....you addressed testing for syphilis

But what are my risks of HIV with this exposure and should I get tested?

I am truely sorry doctor....I apologize for frustrating you....you have answered my questions and I thank you.....

Sigh.............. Are you reading my replies?  Yes, you would have had a chancre.

This thread needs to end now. Further repetitive questions will be deleted without comment.  EWH

Last post....just need clarity...so I would like to restate things from your post...

If I had syphilis...... a chancre would have appeared by now (5 weeks 3 days).  

no need to worry about now until the 90 day mark.....

[Edward W Hook, MD]

Thge frequency of chancres at 90 days is vanishingly rare.  So uncommon that I can not put a figure on it.  

Time for the "what if" questions to cease.  As I said before, it is (past) time for you to move forward, not dwell on the past. EWH

Sorry Doc I did have a question, more for my understanding...

I know you said that I would have seen a chancre by now, but can you explain the published 10-90 days with the average being 21 days?....so in theory is it still possible for a chancre to appear at anytime up to 90 days?  is there a true "all clear" is it 90 days?  is there percentages on the time it does occur?

Doctor,

Thank you so much for answering my questions.  Your answers are very straight forward and understandable.....thanks again.

Welcome to the Forum.  Acquisition of syphilis from oral sex is very, very rare and almost all such cases occur when the interaction is between men and other men, not in heterosexual relationships.  Furthermore, while it is often said that one needs to wait for 6 weeks for a definitive blood test result, the fact is that at this time virtually people who had acquired syphilis would have a positive blood test.  Your risk is miniscule and a test taken at this time should be considered definitive in your situation.  With that as background, let's work through your questions:

1.  Yes, chancres are hard to miss.  If you had had one it would have occurred by now.
2.  STDs can be present without symptoms.  In your case however you have been tested for the STDs that are most often asymptomatic- gonorrhea and chlamydia.  I would not worry further about STD at this time if I were you.  
3.  Personally I don' think it is necessary form a medical perspective.  the reason for testing would be for your own peace of mind.
4.  Yes, you can be comfortable that you did not get an STD from the exposures you describe which you could then transmit to your partner.

Hope this helps. Time for you to move forward and stop worrying.  EWH
