Husband has never made me orgasm

I’ve been with my husband for 4 years and he has never made me cum. Not from him playing with my clit, eating me out, sex, nothing. I try to tell him how to do it, what pleases me but as soon as I’m almost there he moves his hand or tongue, even when I tell him not to move. It ducking frustrates me! Like four years I’ve given this man so many fucking orgasms and he can’t even give me one. Also, my husband is the first man I’ve ever slept with or done anything sexual with and I feel disappointed that this is what I’m stuck with(i chose to wait until marriage for sex, please don’t say anything rude about it)
