If you have any burning sensation in urine.. get an urine examination done.. check your sugars.. and if sexually active consult physician for furthur tests.

Hi... It is due to smegma, which is collected under glans penis.... Normally, a healthy foreskin can be retracted for cleansing and smegma can be removed by washing. The fact that it is a superficial substance renders its removal easy, provided cleansing is performed with regularity. Particular attention should be given to the depths of the foreskin where smegma is liable to lodge in the pocket between foreskin and glans....
