In my opinion, you should not use the vibrator every time you masturbate. Now some women can only have an orgasm with a vibrator. If that’s your case, then there’s nothing you can do, but if you can learn to have orgasms without a vibrator, then make the effort. Of course when you say you want to have an orgasm during sex, I’m guessing you mean during intercourse. Most women do not get enough clitoral stimulation from intercourse to trigger the orgasmic response. Some can if they become very aroused during foreplay, and some require clitoral stimulation, which could take place during intercourse if they’re using the right position. Others find the act of intercourse too distracting and so need to be given an orgasm either before or after intercourse. But at this point, you probably don’t yet know where you fit in on this orgasm scale, and if you are hooked on the strong sensations of a vibrator, then you won’t be able to find out. So try weaning yourself and then see what happens.
