Help...again (don’t respond with “go to doctor”)

So about 2 weeks ago I was diagnosed with a “UTI” and it took a whole week to go away. I was peeing frequently (clear and no pain) and felt a tingling and twitching and pressure on my area but I couldn’t tell if it was my clit or urethra. It went away but it came back today after masturbating. It’s the worst feeling ever and it’s super uncomfortable and I pee over and over. This is stressing me out because I can’t see a doctor as much as I’d like to and have no one to talk to. I’m worried that I was misdiagnosed and may have something worse? I’m just hoping someone whos experienced the same thing will respond to this. Everyone so far has told me that the twitching and pressure is not normal for a UTI but my doctor insists that it is.
