I can only orgasm with a water faucet, why is this??

The title basically says it all. I've tried everything and I mean everything by myself and with my boyfriend except penetration, and until a while ago I was wondering if I could even orgasm at all. Then, I remembered that I used to masturbate putting my clit under the water faucet, and when I tried that I has multiple, amazing orgasms that left me in a state of pure bliss. I feel so frustrated and angry because I feel I will never be able to get there in any way except that. Why even get intimate with someone when I'll always be feeling horny, frustrated, and unsatisfied afterwards, and fucking water feels better down there than an actual person? How can I fix this?? Maybe it's a mental thing idk
