I develop a small cut under the tip of my penis on the shaft after having sex. It looks like the skin is cracked, but it is a slight open cut. When I dont have sex the cut is gone but on occasion u can see a slight outline of where it was. After Sex it will heal up in 2 to 3 days and the area may stay a lil red for 5 +days, it is less than a 1/8th inch long, But when I have sex again the cut open up again in exactly the same spot. I mainly only get it on this one spot, left side of my penis, under the head, on the shaft . I apply Wockadine cream during cuts & cracks. Please sujest me a cream for permanent heal
