My glans penis (head) feels sharp pain when I touch it after retracing my foreskin. I am 24 year old virgin. I do not feel pain when the glans is covered with the foreskin but if I try to touch the exposed part I feel pain. The glans is somewhat red and is very sensitive to touches. If its left exposed and touch underwear or even the side of thigh area, I cannot bear pain. I do not know what to do? How to make it less sensitive to touches?
