I have had red dry marks toward the tip of my penis. They just look dry, pain, mild flaking. I know it not an std cause my girlfriend has been checked. There is no discharge. I look it up and it says yeast or psoriasis. Iv uses psoriasis cream but I feel like it almost makes it worse than if I just let it be. I'm and athlete and sweat a lot. What can I do to make it go away without going into an appointment.
