Maybe so, but the hairs are a natural defence mechanism to trap dirty stuff so it doesn't get to their pussies. When you're fucking them or going down on them, you're going at those hairs from the outside. Any dirty stuff will go onto YOU instead. Eg. The residue from the last punters sweaty salty balls, maybe some poo residue accidentally got onto it when she was going number 2, etc.
So, it may be good for the girl, it's definitely not good for us bro.
