I think there are two ways to look at this, firstly you have a female that is unhygenic, I once went down on a woman that had the equivalent of knobcheese round her clit, needless to say I did not continue it was for want of a better word minging. There is no excuse for poor hygeine either male or female. Not taking care of personal cleanliness is very important both to males and to females, and yes an unwashed vagina can sometimes be off putting if you have to prize it open like a cheese toasty (grilled cheese sandwich for our colonial friends over the pond) then its a non starter.
Now then secondly, you have the pure sexual essence of a woman, the smell the taste can be amazing, mmmmmmmm going down on a woman after she has been working out, the smell and taste are unbelievable, that is different in my opinion to poor cleanliness.
So poor hygeine bad, pure womanly smell good.
Try everything at least once, twice just to make sure! Sorry I havent been around for a while guys, hoping to make up for lost time!! Love you all!
