I had sex for the first time 5 days ago (we used protection) and since then, at the end of every pee I have been burning, it’s just at the end and it’s not horrible, but it burns a little. I'm taking something soft for the urinary tract infection but it doesn't go away, then I thought it might be because I had my first time sex, so could be some pain after it? But it was 5 days ago, is it possible?
