BO

I once knew a man who said that he broke up with his girlfriend because his natural scent had changed.  Obviously, there were other reasons, but he stated that as one of the reasons.  He said that he could not stand his smell; it had changed with this girlfriend.  It is something that people don't consider anymore, but scent may be an important chemical signal for other people.

Ever since then I have been concious of my smell and how it changes.  Most of the time I wear the appropriate doses of antiperspirant and deodourant, but there are times that I don't.  I don't wear deodourant because it tends to be strongly scented and strong scents bother me.  Antiperspirants stop sweating from occurring and thus stopping the musk from expressing.  

Not wearing protection has allowed me to smell myself.  It is not an unpleasant scent, more like a combination of musk and Doritos and for the record I don't eat that many bags of Doritos, perhaps one bag a month on average.  I have also noticed my scent change too.  Activity does not really change it, I can be working very hard and notice very little scent, but my state of relationship status does alter my scent.  When I have a crush, my scent is more subdued, but when I am mentally single, it becomes much more noticeable, both in strength and amounts of scent.

I wonder what the effect of scent is on other people, subconsciously and consciously?
