Facial hair - that depends on the guy. Some men look better without it. I do like beards and mustaches when they're nice and soft. It can add so much to the oral experience
. Scratchy and scruffy however leave beard burns that are quite annoying and uncomfortable.
Chest hair - I love a hairy chest as long as it doesn't creep up over the shoulders to the back. *shudder*
Ass hair - UGH!!! sorry Joe
Scrotum hair doesn't really bother me, but I do like the crotch area trimmed or shaved so it doesn't tickle my nose when I've got a cock all the way in my mouth.
I think that answers your questions.
