Hi, your symptoms and mine match pretty much completely.
Is your smell worse after a bowel movement?
Is your smell worse depending on what type of bowel movement you have? With me if i have diarhea i cant even go out the door cos i smell like the type of bowel movement i have.
Do you have painful/Non painful internal hemmorhoids?
If so this could be a possibility
"Due to increased pressure in the veins of the anus or rectum, hemorrhoids develop. Having hemorrhoids can affect other health related issues such as oneís odor. Development of hemorrhoids usually entails foul odor due to inadequate closure of the rectum, thereby allowing rectum walls to seep out. As this happens, feces can become stuck around hemorrhoids thus intensifying the leaking smell greatly. With a semi-open rectum, allows unpleasant Body Odor to leak causing the hemorrhoids to smell."
Also you talk about the never ending wiping, is there a chance you are missing a bit or not going deep enough and the smell if intensifying due to the sweating then seeping out?
