After vigorous masturbation, my foreskin was sore, it then started to itch which has now subsided but there is a red rash on the glands and small sores round the base and foreskin also a very small flat white spot near the frenulum. I visited a doctor and he said it was herpes but only by sight alone. The last time I had sec was just over a month ago and it was protected. I guess I'd just like a second opinion.
