Hello, I know I have some warts or something around the outside of my rectum but recently I felt a bigger lump inside my rectum when I was wiping with a wipe. When I showered, I could feel it when I was clean there and it felt like a pimple about the size of a bb. I took a closer look today and it has an opening on the top and it sort of looks like you can pull the sides down and the inside will come out sort of like big pimple that you pop the top and it leaves a hole opening with the inside showing. Like another layer with the top opened up. Anyway, I was wondering if you know what it could be. It is along the top or should I in the inside about 1/2 an inch where it starts tightening and on the closes to my testicles direction. Thank you.
