I've experienced this personally, women who have said they love my natural scent (when clean but not wearing cologne). I've heard this is related to pheromones and Major Histocompatibility Complex (MHC), suggesting a biological compatibility signal for healthier offspring.
-
Is this attraction a real, documented phenomenon in human psychology/biology ?
-
How does the mechanism actually work ? (Is it truly MHC-based in humans ?)
-
How strong is the link between scent preference and overall relationship compatibility, in both scientific studies and anecdotal experience ?
