I have whitish yellowish substance around the vagina area and all around. It is very fishy smelling and I don't know what it is or how to get rid of it. I have had it all my life and I have not started my period. Any help?

It sounds like a yeast infection - if it never clears up you need to see a Physician.

It is an infection, if you have had it your entire life, it needs to be looked at.

And I will add a word of caution about over the counter products which can mask symptoms and, in fact, make the problem worse.
