I just can't

It pisses me off so much I have never had an orgasm. I have been eaten out, fingered and 69 but still no orgasm. Don't get me wrong it still feels amazing and I masturbate almost every night I just don't know how to make myself come. A lot of people recommend to rub the clit but idk how to do it properly. If anyone has any hints/suggestions or just anything to help me please do :)
