Hey,
About 5 days ago I lost my virginity. I experienced very little bleeding after (just the next couple of days after sex) and then there was no problems. About two days ago, it started to sting a little after I would pee, and it still hasn't gone away. I was wondering if I should be worried about a UTI, and if so, would it just go away on its own, or should I go see a doctor; or, is a sensation like this an aftermath of having sex for the first time (and if that's the case, will it go away on its own?) ?

Also, if it is something like a UTI, is that an infection only caused by sex, or are there any other ways to contract it? If I have to stop by my university's health center to get it (UTI) checked out, I'd rather not have my parents knowing that I have had sex.

Any help on this topic would be greatly appreciated
Thank you!
