Well, I'll tell you about my preferences and what I know of those of my friends. I personally prefer that a girl be shaven, or at least, that she practice some grooming standards. Though, it's not necessarily a "no-go" if she has a bit down there.
That being said, I do know people who have told me that they've gotten up and walked right out upon discovery that a girl does not shave. Up to the point of about to have sex. Just said "Nope. Bye."
With that, I know some people who prefer it (not as many as the above two categories, but they exist).
It'll be largely dependent on any future partner. If I had to suggest what most guys prefer, I would say definitely shaven. I'd say you can't go wrong that way. However, if someone says they prefer it. Well, it grows back.
I prefer pubic hair. How much depends on ethnicity. Mostly I prefer a bikini trim with an inch away from the edges. Exceptions are blacks which I prefer shaved and light Asians (Chinese, Japanese) that have lush straight, well defined patches (like the well known Aika Miura), to whom I would sing that winter classic: "Let it grow, let iet grow, let it grow!"
