Hello. Can anyone tell me what they think this might be? Not raised. Not painful. Not filled with fluid. Just small red dots that appear and disappear on the head of my penis. Been for tests etc, which all came back negative for STIs, though GUM clinic only tests for herpes when there are noticeable sores - they swabbed previous red dots and tests were negative. Though I'm still worried it could be herpes. Or is it fungal/balanitis? Please let me know.
