I've never been with a "hairy girl", but I don't think I would mind all that much as long as she showered on a regular basis.
And as for the muff, I'm not that picky. If it's trimmed and maintained that's fine, but it bugs the shit out of me when a girl has a tropical rain forest going on between her legs. (i.e., Demi Moore circa the '80's.) XP Yiiccchh.
