I just found this thread, and my $0.02.
1. Wait till your married (the night of), it's worth it.
2. Shaved is MUCH better (you and her).
I've been married for 5 years now, my wife and I both just started doing this and sex is much better (and frequent).
I've got one question for the ladies who don't. Why? You shave everything else on your body, why stop there?
