UTI??

I had sex with my boyfriend for the first time on Saturday (we had sex Sunday too) because we had after prom at a lake house with a bunch of friends. Our room was upstairs away from everyone so of course we had sex lol but it was sweet yet rough like really rough and it hurt sooo bad like it wasn't enjoyable at all and I went pee afterwards and it burned sooo bad and I'm still sore and it still burns... UTI? Or am I just super sore/something is torn?
