Make sure that you're relaxed and in the mood when you use your vibrator. Fantasize, read some sexy stories, or look at porn if that gets you turned on. Not everyone needs a vibrator to get off, but it can make the experience even more enjoyable. After you have your first orgasmic experience with a vibrator, you'll probably find that you want to continue using it at least some of the time. Or maybe a lot of the time.
