After that you mention that you might of have yeast infection.. Have you went to the doctor about that yet? And of course if you use a regular body soap and it will irriate the labia and the area of vagina. So you should and must see a doctor immediately if you want the burning to stop because using soap isn't going to like the thing lol.. I have similar experience in the past and it isnt funny.. Yeast infections are called nusiance little twerk and it is painful.. And embarrasing.
