My a black women I have notice on both size of my vaginal area and inside near both labia a bleach or white discoloration what can cause this

Ashy vagina, Hah!
Is it remnants from discharge, or dryness, or actual discoloration?
Is the texture different than the normally colored areas?
Urinary tract infections contain bacteria that can dry out skin and make the skin appear to be discolored.
There are also fungal infections that are mostly benign, but can cause skin discoloration, and can be taken care of with a topical antifungal cream.
I'd see a doctor for a more specific diagnosis.
