WOW I have almost the same story as you! (for the development of the problem part)
When I was a teen I started to have a constant smell... I thought it would be normal puberty stuff... But the smell just got worse. It was a fecal, sulphur, garbage, beer smell. I now take charcoal pill and chlorophyllin pills since many years to reduce the smell.
I started noticing the irritation effect in college. The whole class would get "allergic" reaction within an hour. IT WAS VERY VERY WEIRD. (It's still is...). I have tried a lot of things of fix the problem... But nothing worked... Other than just meeting people outside with fresh air.
Still no cure, but I am just very happy to have just found this website... And especially the PATM forum here:

TO EVERYONE WHO DON'T BELIEVE THIS PROBLEM:
YES --- IT IS AN EXTREMELY WEIRD PROBLEM. I just wish I didn't have it.
Like I say in the PATM forum of this site: go search for "weird disease" on Google... A lot of stuff are weirder and proven. Even TMAU is listed in some web site...
