I had "Rough" Sex recently. During the sexual intercourse I went dry. Afterwards I went to the bathroom and it burnt when I urinated. It has been a few days now and I still have the burning sensation and I've been running a temp. I have also notices what looks to be blisters on just a small area of my vagina. That was never there before the rough sex. What could be wrong with me? And could those blisters be from going dry and having sex? By the way I've gotten checked for std's and came up clean and so has my sexual partner. Help!

Maybe something got torn I will suggest visiting a obgyn

You could still be burning from rough sex or you could have a UTI or other infection.

While it could be the rough sex, it does sound like an infection. And tests do not always shows STD if they were just caught and of course they can be caught after the test

Blisters? I'd see a Physician, and I wouldn't waste any time making the appointment.
