Put your mind at ease and go to the doctor to get it checked out. These are the sort of things that turn you into a man. Its not embarassing unless you get a hardon when the doctor plays with it. Even if you do its not the end of the world. Doctors are very professional and see that sort of stuff all the time. You will feel better for sure after you've been. They won't chop the foreskin off unless its absolutely necessary.
How've you been washing the prick if you haven't been sliding the top off?
