Infection that makes the glans white and without sensitivity, is it a fungal or bacterial infection?

Inflammation of the glans penis (balanitis) is common in uncirumcised men. It could be either fungal or bacterial. Start by retracting the foreskin and washing with soap and water 3 times a day. If that doesn't clear it up within a few days, see a doctor. Good luck.

We are presuming here that the color change is due to an infection- which is a speculation not a diagnosis. The glans has to be seen and examined for proper diagnosis. pl see your doc or a urologist
