Do Most Women Need Clitoral & Vaginal Stimulation to Orgasm?

Dear Dr. Betty,
My problem is something on which I've done a lot of internet research, and I've yet to find a satisfying answer to my problem. I began attempting masturbation (with my fingers) at the age of 13, and had no orgasms. It felt nice, but I never climaxed. Manipulation of the clitoris was not satisfying to completion, nor was vaginal fingering. When I was 18, I bought a vibrator, but it did not make me come, the incessant buzzing only made me numb. Reluctant to lose my virginity to a fake penis, I waited until I was 23, got fed up, and bought a dong.
