well the same thng happend to me like that night when i went to pee my peeing felt diffrent and it burned alittile but it cleared up after i soaked in the tub it should go away but the first time i used a condom but it shouldnt be no problem
It could be a uti or std. Go to a doc for testing and always use condoms.
U may have a urine infection, i would go see the doctor
