What causes a ring of discoloration on the shaft of penis?
Patient: Hi,I'm a 15 year old male  so lately I'm really worrying about my penis, mostly because there is a ring of discoloring going around the top of the shaft, and also there is numbness on the skin down the front of the shaft why is this?????  I exccesivley masturbate, and I also have a very poor hygiene history I am ashamed to say:( Doctor: Hello,  No need to worry from now on you can take care of genital hygiene. Your issue - it can be candida infection or infected smegma. Daily washing with saline water can help you. If you can share a picture for better understanding - i can help you better.  Hope I have answered your query. Let me know if I can assist you further.  Take care  Regards, Dr S.R.Raveendran, Sexologist
