Burning pee

I know this is so TMI but I need help. Today I’ve been having pain at the end of my urethra and burning after I pee. I’m almost positive I don’t have a UTI because I peed after the last time I had sex and there would’ve been symptoms before today. I’ve also had them before and this feels slightly different but I’m scared it is a UTI cuz I just can’t afford to have one right now. Any tips or advice on how to get rid of this random pain?
