Burning

My girlfriend and I had sex for the 1st time, she was my 2nd and im her 1st, well its been about two weeks and it burns her when she pees, she went to the doc and its not a uranary track infectin and neither of us have an std, what could it be?

well its probably because her hymen broke.
her hymen is a thin piece of skin that is stretched across vagina
think, when you get a cut then get water or soemthing on it, it stings.
and this has happened to me too, dont worry about it. althgouh if it continyes for a long time go back to the doctor.
