[Question #5646] Oral sex std risk

Long story short, I am 29 and have only had sexual intercourse with my husband who was never with anyone else. Back in 2010 I started having burning in vagina, brown discharge, WBC in urine but no infection (this has happened many times after). This was maybe 3 weeks after having oral sex with an ex bf who I found out cheated on me. He and I never had sex, only oral. I immediately freaked out and had every std test available done by blood or urine. All negative. Fast forward to 2015, get similar symptoms, mind you, now only with my husband and repeat gonorrhea, chlamydia and herpes tests. Negative but was treated anyways by doc.

Now again, I weeks post partum, having the same symptoms, ob asked if I was worried about STDs, I said no, but then freaked about the past. What is likelihood I had contracted STDs from my ex years ago and it went undetected? OB took a cervical swab and is testing for all types of yeast, bv and trich, chlamydia and gonorrhea. What is the likelihood of these STDs from me receiving oral years ago? Are all forms of test reliable? (Cervical swab, vs vaginal swab vs urine) 

My biggest worry is my son who is 8 weeks and unknowingly passing him one of these bacterial STDs and getting conjunctivitis which leads to blindness :( I also read about pneumonia caused by chlamydia.) Worried to death for my son.

Welcome to the Forum and thanks for your question.  I'll be glad to comment.  You can be confident that the irritation and discharge you have experienced is not due to any STI.  The 2010 exposure you describe was low risk- most persons do not have STIs and even when they do, oral sex is a biologically inefficient means of transmission.  Most importantly however, you have been tested repeatedly with negative results.  (There is typically no significant different in the sensitivity of vaginal swabs, cervical swabs or urine although vaginal swab specimens are typically slightly more sensitive than the other types of specimen) Currently available tests for STIs are among the most sensitive tests in all medicine.  I urge you to believe your test results.  It is important to also mention that there are many other causes of inflammatory vaginal discharge in women- these include systemic inflammatory diseases, allergies, and on many cases, no obvious causes. 

I urge you to believe your test results.  No further STI testing is warranted as long as your relationship is mutually monogamous.  Your son is at no risk for STI from your discharge.

I hope that this comment is helpful.  EWH

Thank you. Are gonorrhea, chlamydia and trich even relatively possible via oral in general? Everything online tells you something different. It's hard to know scare tactics vs reality.

Much of what is said online is incorrect - either out of date, taken out of context or just plain wrong.   Trichomonas is not transmitted by oral sex.  As I said before, your repeated tests prove that you did not get gonorrhea or chlamydia from your oral exposure nearly a decade ago.  EWH---

Thank you for the info, it is much appreciated. My last questions to close out this thread would be

1.could any recent antibiotic treatment during that time (amoxicillin or the like) cause false negative results? 

2. Is it possible for gonorrhea or chlamydia to lay dormant and not cause symptoms for years? 

3. Could these stis be transmitted in any other way, not sexually? Through shared items, toilet seats, etc.? 

4. Could either infection be confined to one specific area such as cervix and would not show up on a urine test?

I do believe I have no risk, this is mostly for added knowledge. I appreciate your expertise and promptness

1.could any recent antibiotic treatment during that time (amoxicillin or the like) cause false negative results? 
No.  

2. Is it possible for gonorrhea or chlamydia to lay dormant and not cause symptoms for years? 
Extraordinarily rarely,. In such cases however, tests for gonorrhea would be negative.

3. Could these stis be transmitted in any other way, not sexually? Through shared items, toilet seats, etc.?
No.  The idea of getting STIs from inanimate objects like toilet seats in an internet-based myth 

4. Could either infection be confined to one specific area such as cervix and would not show up on a urine test?
Yes, a urine test might miss a small number of infections.  A cervical or vaginal swab test however would not. 

I hope this helps.  I urge you to stay of the internet and accept that your dalliance so long ago is not the cause of your occasional vaginal discharge.  As you know, this is the third and therefore final response as part of this thread.  Take care and please don't worry.  EWH
