I have a shiny red patch on my bellend that’s been there for about 10 days. Doesn’t itch or cause any irritation and I’m faithful to my wife (20 years)
Possibly a fungal infection. Try Daktarin or Canesten antifungal creams, obtainable at any pharmacy. If no change in a week. Best ask your doctor.
I have the same situation. Best is to consult with your doctor.
