The pain is on the head of my penis and it's a burning/stinging pain but when I'm not having the pain I can still feel a sore discomfort. My symptoms are:
-I can't wear boxers because when I do I get pain. (I think it's because they're loose)
-I get the pain mostly when I leave my house.
-My head of my used to be purple but now it's gone red and it's also grey on a part of it too.
-Stress causes it too.
-It happens after urinating and ejaculating too.
-There's cracks and crevasses on my penis. (some of them appear and dissapear tho)

I've been to the doctors three times and have had 2 urine tests and been examined twice. Please answer I'd rather die than go on being in pain all my life.
