Possible uti but not sure??

So for the last few weeks I've been having symptoms on and off that made me think I have a UTI but then it disappears for awhile. It's usually when I'm dehydrated but not always. It's like it hurts/feels intense like an orgasm when I urinate then it just feels like my g-spot is throbbing to the point where it feels like I'm turned on but I'm not and it just feels annoying. Sorry if this is tmi!! Usually drinking a ton of water helps and then it goes away for days! Idk if I should call my dr. 😕 anyone else ever feel this way???
