Personally I have always preferred the natural look. In fact, the harrier the better. I had a friend (nilla) once who had hair from her bikini line all the way down and back up the back, when nude she looked like she was wearing a fur bikini. I could not get enough.

Of course, trimmed is better for certain activities, but I am willing to puit up with some hair in my teeth to look at a bush that well developed.
