I had protected vaginal sex with a massage therapist about 18 months ago. The condom did not come off and did not break. I never had any obvious symptoms of STD, but became concerned about Herpes later after I learned that condoms do not always prevent this. Had a full set of tests with tstd.org and was negative for HIV, Herpes, Hep C, Chlamydia, and Gonorrhea. That was about nine months ago. However, in the weeks before the testing I was treated for a bad chronic sinus infection with several weeks of antibiotic therapy.
About a week ago I went to my urologist because of much more frequent urination, including a strong feeling of urgency a few times. I also have what seems like a mild case of urethritis. I've noticed occasional twinges of pain in the tip of my penis, but there has been no discharge and it does not burn when I urinate. The urologist performed a through exam and found nothing obvious, but has ordered a full set of tests. He also proscribed Cipro oral 500 mg twice a day for five days, which I have already completed, and still have symptoms.
I am worried that I passed a bacterial STD to my SO shortly after exposure, then had my infection cleared up by the treatment for sinus infection, and then got it back from my SO recently. The urologist says this is "very unlikely", but I'm very worried, and won't get the test results for a few more days. I'm convinced I have some sort of infection, and would like to know if there's much of a chance it's not an STD. Thanks for helping.
