Vagina BurningšŸ˜©

Help! Okay so Iā€™ve never been sexually active with anyone. But I have tried masturbation. Recently when I use the restroom and wipe, my vagina feels really itchy and it has a burning sensation and the liners I wear on my underwear show some sort of yellow stain. Any idea of what this could be? Or any remedies to relieve the burning-itchy sensation Iā€™m getting really worried!!!
