Penis forehead pain due to masturbation.

Age: 28 years Never Married, Virgin I was addicted to porn since last 2-3 years. I used to masturbate roughly without any lubricant The penis is now paining in the forehead area. Also loosing color and has become colorless near the tip area. Rest of the forehead is red It pains more when erect. When erect then touching the forehead has sharp pain I consulted a doctor before. He told it will heal automatically and advised to exercise Since one year i am eating good food and exercising daily and yoga too. I only masturbate once a month. I have left porn entirely Around one year has passed but no effect is there. Pain has reduced but only a little bit. The area near the tip is still colorless and looks like varicose vein in color There is no problem in erection. Erection is normal It is not phimiosis, I had it checked with doctor I am getting depression due to this and feeling worthless. Is there any ointment/cream which can solve this problem Pictures: http://imgur.com/a/86A6n
