Giggle, giggle.
Just because we're unaware of our odor, doesn't mean it isn't there. Consider the preparations made by deer hunters to avoid having their body odors, both natural and artificial, make the task more difficult.
We are sight-hunters, but deer are scent-carnivore avoiders. If they can smell us, they avoid us.
Also, humans react to pheromones as well. We may not consciously be aware of it, but our behavior gives us away.
Odors and scents are tricky things. They are more complicated than one might imagine. Consider this, for example: Dogs are exquisitely sensitive to even the faintest of odors, yet they willingly subject their digestive and necessarily olfactory systems directly to the source of exceedingly strong odors. Paradogsical, is it not?
Dogs are weird.
