I have a small bump on the outer part of my butt hole,it isn't a wart because i have looked up pictures of them and it looks nothing like that.It is extremely tiny,there is only one and it is kind of white,yet flesh colored.It has stayed the same size for about 3 months,and no more have produced.please help me i am concerned, and it would be great if you could give me a guess on what this could possibley be.
