Had a one night stand with a questionable character. About 10 days later started getting symptoms such as itching/stinging sensation and feeling of discharge (no color) outside of urination. The worst of it lasted a week or so and then subsided. Went and got the full gamut of STI testing. 4 weeks between encounter and tests. All tests came back negative. For a few days was feeling good then slowly noticed the itching/stinging inside urethra again though not as bad as before.
Question is, could it simply be a UTI? Ive never had a UTI before so if it were that would be a hell of a coincidence.
How much faith can i put in the negative results? Enough to start having sex again without worry of infecting someone?
Could it be some other STI that wouldnt be commonly tested for during an STI-specific swab and urine test? Or one that is easily missed in male STI testing?
