So, based on a Rice study, women's brains recognize men's sexual sweat (as opposed to workout sweat, flop sweat, and whatever).
The next step, according to the article, "is to determine whether sweat scents trigger behavioral changes in woman, such as making them feel more or less attracted to a man." What?! Why isn't the next step seeing if men's brains recognize women's sexual sweat?
Also, I think some people can tell the difference consciously. I've seen perfumistas use a distinction when trying to describe similar notes in perfumes (and have done so myself.)
Again, thoughts regarding gender and society spring immediately to mind.
