I'm allergic to penicillin and something inside buildings in England. I never found out what it was, but it gave me asthma and made me sleep with the window open all winter. Never had a problem before or since.

As for smells, I'm in the same boat as Bruce. No problem with body fluids or human or critter, and don't get into a gross-out contest with me. I've been a vet tech and eaten lunch with doctors. Calla lilies are fairly disgusting, but I don't have an allergic reaction. Whatever died in a wall or under the floor smells pretty bad, but no allergy. I've never smelled Axe. (Ebbie, it's a line of smelly products that's supposed to cause women to jump all over the guy wearing it.) I'm allergic to something seasonal around here that isn't in any allergy test I've had.

Maybe it's the invisible long-haired flying wombat (eastern) dander that you only get when they migrate. Who knows.
