I don't wear deodorant, I usually have no need for it. I've asked girlfriends and friends, nobody ever notices anything smelly. I do well at my job. The only time I'm excessively sweaty and smelly is when I work out. I would bet this is the case for a good percentage of the population, it's just that most people don't realize it, because they've been told they need it since the 4th grade, and never went a day without it since...
As someone especially sensitive to smell I applaude your decision to not wear smelly deodorant.
In the same token, you should know that while other people might not detect your BO, I certainly can and will. But I won't mention it - I'll just get my desk moved to the other side of the office and generally try to avoid you entirely.
Just hope that people like me are never in a position to influence your life - because your BO can and will play a factor to those people.
Of the people I've met that claim to have sensitive noses, they seem to usually complain about artificial scents, like too much cologne, "deodorant" or after shave.
The only times I've heard them complain about smelly BO was when everyone else could too and the person in question should have had wiggly smell lines draw around them if they were in a comic.

One of the problems I noticed when I decided to start using scent free products is that it is extraordinarily difficult to find deodorants or products that are truly scent free. I have found that even most of the ones marked as "scent free" or sensitive have a slight odor to them.
Unfortunately, I am not in that part of the population. I sweat quite a bit, always, and it does smell. It's quite obvious if I forgot to use an antiperspirant one day.
I don't think my friends would have a problem giving me a truthful answer if I said, "hey, I'm doing an experiment this week; I need you to tell me if I smell or not".
Just like the last time you encountered body odor or anything else annoying in public and immediately, openly confronted the person about it, exactly as you would have if they had approached and questioned you with a "doing an experiment disclaimer".
It's pretty typical for crass, frank, rudeness applied to on subject to be completely acceptable while speaking freely on another could easily end a friendship.
