Dear doctor, It has been a year since the 3 unprotected oral sex exposure and never any symptoms yet. But recently like few days back han seen a slit in penis gland and went to three different clinic to figure out the reason behind it and got clarification that it was by an abrasion but still can't rest my self. I tested for HIV and syhlipis and they came back negative (4tests). I heard that it can be asymptomatic as well,so confused and hopeless. Please advise me on this. Thanks!
