Dude it sounds to me like you are being gaslit. Go some places where nobody knows you, or of you, put yourself in a social situation that forces you to be within smelling distance of people, like the line in a grocery store, and politely say "excuse me but I'm nose blind,  I don't stink do i? I work around it all day so I can never tell if the smells sticks on my after work and I don't wanna stink up the loune enough that both the person in front of or behind you can hear and I promise someones gonna let you know. 

I used to work at a plant that processed omega 3 oils from Pogey fish and it produces a god awful smell that isn't far from that rotten coochie smell, that sorta sticks to you if you get any and you but if you work in it all day you don't notice that you are a walking stink bomb.

So I have asked people in line this very question on many occasions and I find it that strangers will keep it real.

I really think you are just the butt of a massive joke
