I prefer my women to have some hair on the mound, but shaven or cut really short on the lips. I like this because the lip hair doesn't get in the way of a good eating and I like the feeling of the hair above on my nose as I suck/lick her clit.

As for me, I keep it trimmed short. I haven't shaved since I don't want to deal with the irritation. I don't expect my women to shave either.
