Re: Sex not on the brain, but in the nose: study
I think our pheremones originate in the brain.
The locomotion of the pheremones is attraction.
And just because one is attracted, one cannot assume the other is. I'm sure we've all been thru that at least once...
My experience has taught me, that there is a subtle difference to the mutual attraction. It has a certain "feel" to it.
Things are rarely as they seem on the surface
