My vagina remains wet , I am having pain in my stomach and vagina . My layer is peeled slightly. White discharge flows out of my vagina. All I know is that my boy friend fingered me 1 month back and after that I am having this symptoms . I cannot talk to my parents about it. I am so afraid.Can with time it can be healed itself.

No with time it can cause you a lot more serious injury. With time it may even (depending on what it is) appear to go away but be inside doing very serious damage.
In time it could be many things.

Ok, lets grow up fast, you decided you were old enough to act like a adult and do some sexual things, it is time now to act like a adult as a result of it.

There are many female issues that require you seeing a doctor, this will be one of them. From a serious yeast infection which you can just get, to other female issues.

So you discuss it with your mom about what is happening and she takes you to the doctor and you have it checked.

Welcome to the adult world, you wanted to be in it, so you are, now deal with it as a adult

Okay chill. You have to tell your parents. I'd tell mom, just because stereotypically she's the one to go to for feminine issues. Go to your doctor and get it checked out. Hopefully you'll hear some good news and be relieved. Maybe it's nothing at all, just a different way your body has of cleansing itself. Don't listen if anybody yells at you. Handle your situation with optimism.
