(18 year old female here...)

So I've never been able to succesfully masturbate on my own. I've always just used a vibrator and it usually gets me to where I need to be. Now that I've started having sex (bout 4 months now), I'm beginign to see that its impossible for me to orgasm without the intense stimulation I felt from the vibrator. Now matter what my boyfriend does (intercourse, oral, fingering...), It doesn't seem to to do anything for me. There was time when we first starting having sex, where I would feel really tight, and tingly all over, but it never got anywhere past that point. This feeling hasnt' happened for a long tiem too.. NOW Yes, it feels good and I still have a fun and enjoyable experience with everything sexual that we do, but it upsets him (and me a little bit) that I can't orgasm from the stimulation he gives me.

Have I pretty much shot my nerves from using the vibrator? Will I now never be able to orgasm without it? Also, what if I give it up for a prolonged period of time, will that help? What can I do? I'm kinda fearing that I'm the sorta person that just doesn't orgasm with another person... HELP!? ADVICE?!
