Masturbation tips

So I’ve known about masturbation and I’ve done it for a while now. The thing is, I’ve never been able to make myself cum. My gender is non-binary but because of this post, my sex is female. I’ve been trying to make myself cum ever since I started masturbating but I just can’t do it. I don’t know why. I don’t know if I’m not doing it right or if I’m not masturbating long enough or if I just can’t cum. The only time I’ve had an actual orgasm was (it’s weird but) when I was reading a smut fanfic with my bias of a boyband I’m into. I need help and I want to know how to cum
