Cut at the top of my vagina?

I think it's because the hormones and stress somehow causes an imbalance of the pH of the vagina discharge. And the burning and irritation is constant, because of the pH of the discharge is not normal and there is more discharge when it happens. Your vagina is more acidic than basic. Think about your sensitive tissues around your clitiros being soaked in basic fluids all day....they should be irritated. The irritation stops when your period starts, and I believe it's because the pH of blood is not irritating to the tissues. And it can be yeast too, because when the pH of the vagina gets more basic, yeast can grow...you may notice white creamy or thick discharge....someone can have these paper cuts, with and without a yeast infection...when you get it on your clitoris it can get all swollen and have some white discharge around it. You can also get small tears around our labia if you're having dry sex. I hope this helps....if not sorry.
