<human>: (Xposted from r/sex) 

First off, before anyone yells at me: I've already been to the doctor/gotten tested. I'm clean.

Which leads me to my question. A few weeks ago, I hooked up with a co-worker. She gave me oral sex and we had about a minute of unprotected sex (I know, I know). About three days after, she comes down with gonorrhea. She calls me to tell me, clearly pretty certain that I gave it to her. I told her I didn't know how that was possible, seeing as she was my first partner since the last clear STD test I had had.

Fast forward to today. I call the clinic and get my test results for the test I had after being with her, and after she told me about the gonorrhea. I test negative for chlamydia, gonorrhea, syphilis, and HIV. Meaning I could not have given her the gonorrhea. (Never had any symptoms myself, but obviously I still wanted to get tested).
Now: do I tell her that it wasn't me? Or, since there's nothing else she has to worry about (like having HIV or chlamydia), should I just let it be? We are not on speaking terms anymore, and we work in separate offices so I really don't ever see her. The biggest thing I'm afraid of is her viewing an email from me as gloating or something, and then getting mad and subsequently revealing (either true or false) information about me to co-workers. I have no indication that she's crazy or vindicative, but I really don't know her and I want to be cautious.

Of course, part of me wants to clear my name, since I was 99% sure she didn't get it from me and science seems to be on my side.
What would you do in this situation?

<bot>: Co-worker thinks I gave her gonorrhea, but tests show she got it from someone else. Should I tell her?
