June 17th, 2010. I have been having this problem for about 3 years now I think and I don't know what to do? I smell bad all the time. I used to be really constipated and so that was why but now I have 4 bowel movements a day and I still always smell like I need to have a bowel movement again. When I have a bm even though it may be substancial I still feel unsatisfied, yet I could sit there for an half an hour and nothing would happen.
