Okay, so I have this same problem.
Legit it's so embarrassing and I'm the ONLY person I know of with this issue.
It's getting to the point of me not wanting to do anything and completely isolate myself.
If I'm sitting somewhere for a long period of time and get up it smells, if I'm enclosed in a room or a car, it smells. I smell it on myself, constantly. Even after showering.
I just want to know, will this ever go away and what can I do? If anything, I've tried almost everything.
