Hello, i am 23 years old. From childhood itself i have tight foreskin problem when my penis is large. Its giving pain when i touch my penis head with tip of my finger. So i never tried to do that. But recently while bathing i pulled the skin and washing it. It is suddenly started enlarging so i tried to pull back the skin while doing that suddenly i got pain and 3drops of blood came through it. I dont know what has happend. I didn t had sex before. Please prescribe any thing.
