I am 22 years old and only became sexually active in the last 2 months. In the last month I have noticed a white film appearing over my outer vagina lips and vulva. I have gone to my doctor an been tested for both stds and yeast infections but they all came back negative. I am washing every few hours as the white coating continuously returns. It is not a watery discharge but more like a playdo texture. It itches and after I wash the area is very rare and irritated. Please Help
