I don't know about anyone else, but I am fed up of finding girls with shaved pussies who have stubble, which is unpleasant to feel with your fingers and even more nasty on your face
I am always careful to shave my face and bits very scrupulously before a punt because I know that girls don't like to kiss a guy with stubble and reverse oral is often uncomfortable for them if your scraping their aunty Mary with your sandpapered chin.
So why can't they be just as careful themselves? As you lick northwards, it can be like rubbing your upper lip on Velcro
I much prefer a well waxed pudendum to get stuck into - or a trimmed bush
