Now, the big question is, did you damage yourself using vibrators? Short answer: No. Long answer: Because our society tends to think of masturbation as "lesser" and, for heterosexual folks, puts a lot of emphasis on a woman getting her orgasms from her male partner, this question comes up a lot. There can be several reasons why we orgasm with vibrators and not with other stimulation. Generally though, here's how I think about it: When we teach our brains how to do something, they get annoyed/confused when we do that thing in a different/harder way. Think about how we panic if we don't have our cell phones on us but if we stop and think about it, and I may be dating myself here, we remember that we didn't always have a phone with us everywhere and we got by fine. It's kind of like that. Your brain knows that you can orgasm with a vibrator and so when you're in a sexual situation it's kind of sitting there going, "Where's the thing we use for this? Where's that thing that makes this work?"
So, you have a couple of choices here. You can introduce your partner to your vibrator, or you can take some time to cultivate vibrator-less orgasms by teaching your brain about the different paths to orgasm. Call it a vibrator vacation. Or you can do both, keep your vibe around and play with letting your brain connect with the sensations as well.
Whatever you decide, it's all good and I promise, you are not damaged.
NOTE: Taking some prescription medication can change the body's responses and in those cases sometimes extremely strong vibrators seem to be the answer.
