Can’t jizz

I’ve never been able to have an orgasm. it feels good when i hold my hands down there (idk how to explain it) and it’s something i’ve always done since i was a child so could that be a reason why i can’t? i got numb to it? it feels good, but not enough to come close to having an orgasm. I have tried a vibrating back massager and bathroom faucet but none did anything for me. when i touch myself, i can feel the clit with my fingers but it doesn’t feel good/ like anything. I can get wet and horny but that’s about it. Any tips? 😐
