So about a week ago I went to the doctor because I was experiencing a burning sensation when urinating, I took a urine test and the doctors found nothing wrong so they gave me anti biotics and the peeing problem is getting better. About 3 days ago this popped up on my foreskin and I couldnt figure out how it happened. They are sore but dont botherme unless irritated and dont discharge or anything. I did have unprotected sex 1-2 weeks before i had these symptoms. Does anyone know what this could be??
