I prefer trimmed myself. I think public hair on a woman is sexy, but, along the same lines, I don't really want to feel like I need a weed-whacker if I would like to go down on a playmate.
But I certainly won't turn my nose up at shaved either.
It really has more to do with the personality of the woman then anything else. If a woman is sexy, then that's all there is too it. If that means I end up with some "tactical floss" while pleasing her, then so be it.
