Make sure yours is shaved, and if she still has no clue, tell her that it's a turn on when it is shaved. I wouldn't tell her that it is a turn off when it's not shaved, even if the two mean the same thing, don't tell her that it turns you off when a girl has long bush hair, cuz you have already been with her intimitly, and then that would give her the impression that she does not turn you on, unless she is so clueless she doesn't even realize that her shit is long.
