Stimulation issues

I honestly think there is something wrong with me...more like my clitorus. I've only felt it be stimulated once in my life and at was one of the first times I've been fingered. Since then I haven't felt anything. Not when my SO tries to stimulate it and I can't even stimulate it. I'm not one to masturbate, but I thought that at least i would be able to stimulate it. Is there something wrong with me? Any tips on how to stimulate it with/without vibrators or any other toys? Anyone else have the same problem?
