Do you suffer from persisting and recurring abdominal pain, diarrhea, vomiting, acid reflux, constipation, any symptoms that may be cuase by food intolerance and/or other stomach problems such as ulcers or polyps? do you have hemroids or anal fissure or experience incomplete bowel movements?? you say you have two b.m a day, right!?do you mean that you have two complete bowel movement a day or do you just poop twice a day??? there's a difference, trust me!!! I had three (sometimes more)b.m in a day but sometimes i still felt incomplete.
If stomach problem isn't an issue for you... do you think maybe it has something to do with emotinal responses? think back when this odor problem been brought to your a attention. I believe you said about a year ago, people stated to notice this odor coming from you, did you have anxiety during those times when people detect the odor??
