Sexually frustrated (sorry for posting this in multiple groups)

Hello ladies! As you can see from the title, I’m sexually frustrated. I am fully capable of having mind blowing orgasms (and even squirt!!) , but only with the shower head :( Any sexual partner I have had has not been able to give me an orgasm, and I have never been able to get to give myself an orgasm with my fingers (clitoral and vaginal stimulation) or even grinding on pillow. Yes, I have tried watching porn to loosen up (literally every single kind there is and it just doesn’t do it for me) and I have spent countless hours rubbing my clit and fingering myself and grinding to try to figure out how to cum without the use of the shower head. Nothing is working and I’m so frustrated because it seems like most women can get off by rubbing themselves and obviously their partners can get them off too. When I’m being eaten out I don’t even feel anything (and I’ve had multiple experienced sexual partners that knew what they were doing)?? I even tried taking a “tolerance break” from the shower head for a month to see if I had just somehow desensitized my clit and even after that, my fingers weren’t doing the job. I have tried rubbing (lube and no lube) tapping, flicking, literally everything and its not working. I obviously want my partners to be able to make me cum too but that’s kind of impossible since the only thing that works is the shower head. Some may say that I’m thinking too much into it and I’m too tense to orgasm but that’s really not it, it just doesn’t do much for me and I get distracted and bored and then frustrated. If anyone has any ideas, I would appreciate them!
