About 4 or 3 days ago I noticed some type of dry skin on the head of my penis and there was what it looked like dry dead skin peeling off but not that much it was just so small I could barely see it but I tried to get it off with my fingers but it didn't worked and then I got this red small bump sometimes red or sometimes skin color. Its not hitching at all and the first time I noticed the bump I just put lotion on it and it started go fade away but then I had sex the following day and it got bigger but not that bad. What can I do it about ? Could it be a wart? I got some pictures of it so if you could tell me the best way to send you the pictures so you can help me that would be good too.
