oh man. that was the worst part for me too. if you have a cold baby wipe hold it on your vaj the whole time you pee. obviously your gonna get some on your hand but omg. its the only thing that made it not hurt for me and the coldness feels good.
use the sqirt bottle they gave you sqirt cold water on it while u pee it helps .... i had to do that to help that cuz yea that stuffs feels like a fire
