But from what you explained and if she had gone to see the doctor, the sympton looks like a UTI.
I agree with this. My gf has gotten a urinary tract infection after we've had sex. It's moderately common among women, a bit less common among men, but overall easy to get. A check at the doctor's office can confirm it and anitbiotics will clear it up in about a week.
To the OP, if you're unsure then just get another STI checkup or a second opinion from a doctor. It's all relatively easy unless you have personal insecurities about it.
