First time having sex now it's painful to pee?

[Atlantababyga]

I'm a 16 year old girl and I had sex for the first time with my boyfriend who was not a virgin. I knew it was supposed to be painful at first and it was. Later it felt fine but I was a little sore. I assumed that it was normal and didn't really pay much attention to it. Right after I went on a 2 mile run (like I normally do). I went to sleep and everything felt fine just slightly different down there. I figured nothing was abnormal but I woke up this morning and went to the bathroom and urinating was so painful that I started crying. It was the worst burning feeling I've ever had. Can someone please explain what might be happening?

You most likely have a urinary tract infection. It would be way to soon to have any symptoms from an STD. Many people get UTI's, it's common. It could have been from the intercourse or you may already have had one starting. See your Dr and tell them your symptoms. You do not have to say anything about intercourse with your boyfriend because even virgins get UTI's. Do tell your mom about burning while urinating and that you think it's a urinary tract infection. She can get you to the Dr because if this is what's going on you will need antibiotics. They will take a simple urine test and go by your symptoms.

Depending on when you had sex, it could be a std.  I think we are both from the atl by the way.
