I like mother nature to take care of that, but in all honesty I kind of like both hairy as it can be and clean shaved, no in-betweens though, it has to be either all hair or no hair at all
Shaved, as someone with genetics for a lot of body hair i'm familiar with how it feels and how easy it is to get dirty and how hard it is to clean, plus the sensation of getting hair in your mouth is terrible and it covers the best parts. You want to see your LI wet, you want to see their deepest parts, you want to kiss them all over, and hair will get in the way of all that
Depends on the art style and the particular character. Some archetypes just make sense to not be particularly well-groomed in that department (or under the arms, too), like girl-failures, or the French.
The only place a woman should have hair is on her head. MAYBE a landing strip down there, but better clean shaved. And on the legs, armpits, etc is gross.
