Hi.
About 4-5 weeks ago I had a sexual encounter with a stranger. I was received unprotected oral sex.
After two weeks I went to a specialist std clinic to get examined and tested. I have not had any itching, pain, discomfort, growths etc. the examination and Std results came back as everything is normal. As an extra precaution I took a round of antibiotics while waiting for the test results.
About 2 days ago then I have noticed a faint white discolouration patch on the penis head about halfway between the tip and the edge. It's quite faint but can be seen when I press down on it (kind of like when you have a mosquito bite, you press down on it and the white area stays white). It's very faint but it resembles a rough shape of a square. There's no pain or itching etc and I think if I wasn't so anxious I wouldn't have noticed it.
My concern is that it might be syphilis, as the doctor didn't test for it because she said after the examination/consultation that it wouldn't be syphilis.
Does this sound like a symptom of syphilis or hpv??
Thanks
