My fiancé doesn’t want me to use my vibrator.

He doesn’t want me to use my vibrator. When we have sex I’ve never have an orgasm. Hence that’s the reason why I bought the vibrator. He was furious. I told him that he does not make me cum when we have sex. He said he gets his off, & that something is wrong with my vagina if I don’t cum. He says me wanting a vibrator is just being greedy. I feel disrespected and I feel less than a woman. I am not okay
