Can't orgasm 🙄

My partner and I started sexing and phone sex probably back in September, He always seem to cum when we do it but I can never.. I have to FAKE my orgasms..🙁 I've never oragamed in my life, and I want to experience the feeling of having one. I can't tell him I've never oragamed, He's fingered me and sucked etc etc but I can never orgasm, I sometimes feel it coming but it never does 😩😖 is there something wrong with me?
