I would like to thank Dr. Hunter for his advice, but I do have a simple follow up - I understand that oral chlamydia is rare, and I agree that I do not need throat testing based off of your explanation, especially since it has been over eight weeks,. My question is, how fearful should I be that I passed on a oral infection to my partners penis  8 weeks ago, if I have tested negative genitally ( meaning that he did not re-infect me) can assume that he does not have an asymptomatic genital infection that he has yet to transmit to me? assuming sex once a week?  

Welcome back to the Forum.  As you know, Dr.. Handsfield and I share the Forum and today your question happened to come to feel. In preparing to answer your question I reviewed your interaction with Dr. Handsfield three days ago and agree with all that he said, including that the chance that you acquired chlamydia from the encounter was infinitesimal and that there was no realistic reason to worry that you might have transmitted an oral infection to your partner's penis.  I urge you to be confident not only that you did not acquire chlamydia but that you did not transmit anything to your partner.  ---

You are correct in that I feel immense guilt for betraying a person that means so much to me. I want to move forward with my relationship without this underlying fear. Understanding that repeated questions are discouraged, I will try to move forward following the conclusion of this thread. You stated that I should be confident that I did not transmit a chlamydia infection to my partner. Is this statement based on that fact that over the past 8 weeks, having sex weekly, would have transmitted an infection had one been initially acquired? Since I tested negative genitally there is no real possible way he has yet to re-transmit to me? 

No single factor was the reason for my statement but all of them. When taken together, there is simply no realistic way that you acquired chlamydial infection and transmitted it to your partner.  You really need to get over this unrealistic concern and address your guilt.  Worrying about whether or not you will be struck by lightening (for which the odds are about the same) will not help you address your guilt.  I say this out of concern for you, nothing more.  EWH---

Dr. Hook, I appreciate the concern and am seeking mental help as this stress has caused me a 10lb weight gain. Since this will close my thread, and despite my actions, I care deeply for my partner, could you please answer if a genital infection would have been transmitted back to me during once a week sex after eight weeks? A simple yes or no will do, if you do not feel the need to go into explanation.

As I said above, I see no realistic way that you acquired chlamydia and therefore there is no realistic way that you could have transmitted chlamydia to your partner.---
