“Just a few whiffs of a chemical found in male sweat is enough to raise levels of cortisol, a hormone commonly associated with alertness or stress, in heterosexual women, according to a new study by University of California, Berkeley, scientists.”
This SO makes sense to me! I remember a BF from high school where that was VERY much the case. Of course with the BO factor, FRESH sweat was best. V fabuloso!
