I started noticing a kind of red blisters arround the top of my pennis, after I had sex. It was a few days after the sex night. It started like I was loosing the skin, like dry skin and it would just come off, it was itchy for 2 or 3 times, than it turned RED and it hurt when i had an erection and when I was trying to have sex again. I am very concerned, and I don't know what it is, and there is a cure for it. Can you please help me?
