I have a question about something that has been there for longer than a year but just started to worry me. Around the edge of the head of my penis there is a blue ring like swelling. This does not hurt however. This is right at the edge of the head and not on the skin itself. The skin however, when I pull it back when erect does look like extra skin rolled up right behind this swelling. Not a lot of skin but there is some extra skin rolled up there. Again, this does not cause any pain but it does worry me that it could be something serious. Should I be worried?
