Hello Doc, I am 23 year old bachelor and a virgin, I am getting married in 2 months from now, I have issues with my penis, i Started masturbating at the age of 15, it was like everyday till the age of 19, now too i masturbate at least 2-4 times a week. initially the head of my penis was pink and length was 4.5inches, now it is has gone greyish brown in colour and the length is around 4 inches, if i am fully exited or it will rise only for 3 inches and sperm oozes out, and if i masturbate continuously for 3 days then my waist region and my balls pain a lot for some 2-3hrs. doc please guide me through this issue. i dont want my wife to suffer due to this.
