UTI?? What?? Please help😂😅😬😩😭

So recently I’ve had this weird feeling “downstairs” and it’s making things very uncomfortable. It’s like I REALLY need to pee all of a sudden and then when I go to pee nothing happens or if it does the feeling either doesn’t go away completely or just doesn’t feel normal??

I’m very new to anything abnormal happening down there and am not sure if it’s a UTI or something or whether it’s something that’s happened when my boyfriend and I have been having sex??

Can someone please shed some light for me? I’m too scared to call the doctor (I’ve never had to go for something like this before)
