I really dont know what this is, i have red markings on the right side of the glans which have not gone away for over two years now and on the left side i get a rash of some sort which fades but gets more prominent after a shower or masterbation. The whole of my penis at times becomes like a blotchy red/purple rash which will fade after using a bit of hydrocortisone but never goes completely. I dont appear to have any discharge or burning when urinating and the only other thing i have sometimes is a pain around the belly button area which goes after a day or so. I also get pain at the top of my legs where the groin joins but i think this might be muscle strain with playing football etc. Any thoughts or ideas what this could be would be most appreciated...
