I was a virgin and had sex for the first time recently, and the next I was very sore and it burned when I urinated. Two days later we had sex again, and the burning got worse, it hurt to walk, my vagina became swollen, and I have white discharge that's not clumpy, a high fever and red bumps around my vaginal lips close to my butt. My boyfriend claims he does not have an STD. Can you help me figure out what this is?
