Hi, I have recently been on antibiotics (cipro) and am 4 days into use of a 7 day course, I noticed yesterday that 12+ small flat red painless spots had appeared on the head of my penis , they do not cause me any discomfort or pain, and I have not had unprotected sex, would you be able to help me identify what they are and what a cure could be? Thankyou in advance, gary
