I just squirt/pee but can't orgasm

When I masturbate I usually involve both clitoral and vaginal stimulation, but whenever I touch my clit I feel a build up that always just leads to squirting/peeing (this happens regardless of vaginal stimulation). I say it like that specifically because they feel exactly the same, except peeing normally is honestly more satisfying than whatever I get from masturbation. Like it's technically a release but not in any kind of pleasurable way, it's literally just fluid exiting my body without any pulsing, clenching, or mental effects. I can always continue going afterwards like nothing happened. My legs do twitch a bit leading up to this though so idk whats not working properly.

This happens no matter what I do; I've used hands, vibrators (both wand and bullets), and a rose toy. I also don't think it's an issue with pushing too hard or something because I've genuinely tried to hold it in, but as long as I keep touching myself, it will always come out.

The ONLY time my body doesn't do this is when I grind on the heel of my foot which is something I started doing as a really young child. I think doing this is what gets me to at least have very small orgasms, but I really want to find another way. The amount of force and movement that I require often rubs the skin on my clitoral hood raw, plus I would never be able to orgasm with a partner like this. I'm worried that because I started doing this method so young, my body might've gotten attached to it in a way that anything else doesn't even give me the feeling of building to an orgasm, no matter how good it feels. I've been experimenting with all kinds of different things for years but nothing gives me the same feeling so I don't know what to do. And grinding on other objects such as a pillow just isnt enough for me.

I'm 19(F), have adhd that I'm not medicated for yet, and the only med I'm on is Wellbutrin which hasn't made a difference for me personally with my anorgasmia (I was prescribed for a different reason though). I do have a hard time staying focused and getting aroused sometimes, but there have also been a lot of times where I'm in a comfortable environment, have no worries that I'll be interrupted, no feelings of shame, and feel very turned on, but STILL nothing works. I've even masturbated for 2+ hours straight before. And I feel plenty of pleasure, there's just no tension to it aside from the squirting, which like I said doesn't feel satisfying whatsoever.

Any response is appreciated even if you don't have advice to give! I just feel so lost and hopeless, but I haven't given up yet.
