I've never been with a woman who wasn't at least trimmed.  I wonder what a bush feels like.  It probably smells nasty.  
It smells just like a woman who's shaved unless there's sweat involved.  When sweat is involved, I find shaved women smell worse.  I think the lack of hair allows the ass and puss to exchange sweat juices more freely and violates the sweet pussy aroma with jogger's ass aroma.  
Also, a woman who has a bush feels good to fuck.  I don't know what it is, maybe something primal but it really gets the aggressive side out in you.
