Is this normal?

So I just masturbated for so long that it got to a point where it honestly felt physically uncomfortable to continue. I didn’t have an orgasm (I’ve never been able to have one before, I can do stuff that feels so amazing my whole body is convulsing but I can’t ever even get to that “build up” of tension that people talk about before you orgasm...) and after an hour (yes, literally, a full 60 minutes of rubbing my clit) it got to a point where my clit felt almost painful when I touched it, and it didn’t feel nearly as pleasurable as before. Did I rub it raw?? Is that a thing??

(And god, why can’t I have a fucking orgasm??)

If you guys have heard of this happening before please let me know what it is....🤦‍♀️🤦‍♀️
