Honestly, yes. Every guy has a preference one way or the other, which means you're more likely to be struck by lightning than to find a man who is entirely ambivalent to the forestry down below.
A guy's preference on pubic hair (or lack thereof) is tricky because there's really no way to tell what a guy wants until you're both naked and about to get some work done. Most guys prefer a shaved area, but some guys prefer the exact opposite, and there's no early indication as to which way a guy leans. And it's not like you want to ask halfway through the appetizers on your first date. You're going to discover what he likes the same second he discovers if you have what he likes.
That said, don't get to work with the Mach 3 unless you really want to. Some women don't like the feeling of being completely hairless, and some women don't mind it at all. So do whatever you feel most comfortable with. No guy is worth doing something that makes you feel exposed or unpleasant.
Life your life, shave or don't, and the right guy will come along and find exactly what he's looking for.
