New fetish discovery

There's a difference between the aroma from fresh sweat on clean armpit, to days old unwashed armpit, personally being involved in close combat throughout my youthful days, the former aroma is typical acceptable attribute of an active sportive male physique, whereas the latter is definately not for me, and socially unacceptable. However apart from the scent orchestrated by the armpit hairs, I find the musculature sides of a guy's armpit i.e the back formed by the back lats aka "wings", and the front pecs, both forming the pit physically erotic !
