Help orgasming

I have been with my husband for 7 years and I haven't been able to orgasm from sex. I can only orgasm when I rub my clit and its frustrating. My husband can try to rub my clit and it isn't the same and I can't orgasm.i know it's not just him because I had the same problem with other men. Is there something wrong with me that I can't get an orgasm from other people please help!!! I just always feel numb down there unless I'm doing it.
