Most people have their favorite, fastest route between point A and point O, and they take it all the time. But it's nice to take the road less traveled occasionally, for a little variety. If you could climax prior to the vibrator, you can do it again: it'll just take some practice, some time, and some serious discipline. Try your old way, or attempt to re-create the sensation of your vibrator with your hand, or your partner's hand, penis or tongue. Remember, it'll probably take a lot longer and feel a little different, but relaxing and giving it time might help get you there. If not, don't sweat it--there's no "wrong way" to have an orgasm. In fact, plenty of women wish they had your problem.
