A month ago i was jerking off and my foreskin swole like there was some fluid inside it. It wasn't painful at all. I was able to urinate without pain. No pain in penis or forskin. But i freaked out cause it swole so much. Next day i went to doctor. He took a look at it. Took a blood test and told me it was fungal infection. He gave me some medications. Which worked fine and i was all well. I avoided any sexual activity for a month. Bit after a month when i was masturbating again it happened. I again went to doctor. He gave me same medication again. I dont have swelling now. But it seems that i have more veins on my foreskin than before. What could be the reason. I dont have any pain in any area.
