I developed a discolored mark on my penis It

Patient: I developed a discolored mark on my penis. It is shiny when I shower and dry if I don’t put polysporin on it. I’ve also had a slight discharge and itching on the tip. I also felt pressure when peeing. I’ve been married for 19 years and have been faithful (as well as my wife I think). I’ve looked everywhere online and all things point to a yeast infection. I drink a lot of beers. Can you tell me what I have?

Symptoms: Discolored mark on penis, urine slight burning. Itchy penis top
