I had sex with my girlfriend during the first rounf the condom broke then we used a plastic, she told me that when she pees it hurts as if she's being poured with hot water so what might have happened and what can she do to reduce the pain
from what is sounds like she has got friction burn down there from being dry. you could try an ice pole wrapped in a paper towel and sit it just in her nickers to ezz the pain until it's better also tell her to take a cup of water with her to the toilet i know is seems crazy but tell her pour it down as she pees it may help with the burning pain because the cold water stops the burn from the warm urine and it die-loots it so there is not so much acid in it.
give it a go and tell me how it went...
hope this helped :)
