For the past couple of years I have had some small cuts that look like strech mark lines on my penis shaft near circumcised area. When i start to have an erection, there are a couple areas that hurt, making it difficult to have a proper erection. When my penis is most erect, it really hurts in that area. I suppose this is all due to friction. I have gone to a urologist a few times who says that he sees some plaque areas, but nothing that was a serious problem. He also gave me a perscription for hydrocortzone cream. It doesn't seem to work. I have gone about 7 days, giving time to heal. But when I try to get erect after that time, it hurts in those same areas. You can barely see a tiny scratch mark in the area, which is where it hurts. Do I have to give it even more time without erection to heal? Is it possible I have damaged the area permanently?
