My two year old son had very much smegma deposition on his penis and while passing urine his penis was swollen. I had taken him to doctor he cleaned the smegma deposition by pulling his penis back and he had precsibed micosept b cream . And there after my son  foreskin was easily moving back but his tip of the was red doctor had told it will be normal.. and after thatmy son was telling he is having pain while urinating... Does it cause any harm In future
