Diarrhea, Obstruction In Anus, Yellow Substance

I had diarrhea (little or no pain prior to that) and discovered that something was stuck to my anus . When I pulled it, it seemed to be a stretchy thing and snapped. I pulled more parts of it. It appears to be about 3 mm wide, very, very thin, and a length that I can t determine (as it snapped off several times, and I m not positive I got all of it). Based on the fact that there was enough tension to snap, I would assume I didn t get it all. When I first pulled it out, it was yellow with some lines every few millimeters. After it dried, those lines show up as black marks, but the overall thing was still yellow.
