I am 21 year old male. I think its been one week since I found the problem. Even though my penis foreskin color is dark, there is a dark dry layer formed, looks like patch on tip of my foreskin. There is nothing under the foreskin or on the penis but only on the tip of foreskin. It doesn't hurt or itch but sometimes when i clean it with water it feels burning sensation. It burns sometimes only but not so badly. No blood or fluids. I am not exactly on the situation to see a doctor right away. I would love to hear your thoughts on it and the medicine should I take. Thank You!
