“If your vagina itches and burns does that mean you have an STD or a yeast infection?”
Unfortunately, an itching and burning vagina could be a bunch of different things including yeast infections and some STIs.
The only way to find out what’s going on is to get checked out by a doctor or nurse.
If you’ve had vaginal or anal sex without a condom (or oral sex without a condom or another type of barrier) then it’s important to get tested for STIs.
