I'm a 26 year old male and today I noticed a white spot on the tip of my penis just inside the urethra opening. I'm uncircumcised but practice good hygiene in my genital area. I am sexually active only with my wife. I did notice my gentitals were itchy this pass week but in thought it was dry skin because there was no redness or rash. Then today I noticed that small white bump in my urethra.
