Hi, I have been forced to have anal sex for couple of years, I've never like it and never enjoyed it, and was always painful to me, the problem is lateley I experienced some bleeding during bowel means when am emptying just at that moment and the blood disappear right after that, I dont feel any pain in the anus but I have a horrible right lower abdomen that doesnt let me live normally it is painful when am standing lots or sitting lots so uncomfortable, feels like burning inside my colon,I am so worry and feel so embarassed to talk about it with my PCP, I am so sfraid that I developped infection or cancer, I mention here that I used to suffer from constipation long time ago because of emotional stress and used to have a stress gastro-duodenal ulcer that I treated 15 years ago..please are these symptoms means a cancer/
