These are pimple like bumps that when developing turn a little sore but when in the shower can be squeezed like a pimple. A brownish semi-solid mater come out. I've had these for years now. They are on the sphincter membrane. Maybe only 2 or 3 at any given time. When squeezed the bump goes away but they eventually return at some point. I'm not gay, no anal intercourse or anything like that. Never had a STD in my life. Basically they are like a reoccuring pimple but they aren't pimples. They are always on/in the membrane area.

I don't think they are 'always' in the same place. The material will eventually work itself out and something such as wiping will remove it once it's progresses far enough along. I have not been to a doctor as I've been in Afghanistan for the last 4 years and seldom get back to the states. As for being grouped, the area they appear isn't that large so they are/can be anoy where within the ring and can reappear in the same place. The material that comes out is soft, somewhat of the same consistancy of a pimples material without any liquid. Squashes easily with my fingers. There is no odor, only a little sensativity when it's built up and is near the surface. A simple and easy squeeze with my fingers removes the material. Maybe be a few weeks or month before anything returns.
