Sometimes when i wipe my vagina, burns why?

Toilet paper "burn": If you are wiping from front to back as needed, is it done "roughly"? If not, make sure that the toilet paper does not contain colored dyes or "freshness" products that can irritate the vulva. Also utilize mild soaps like Dove, Caress and Ivory to minimize vulva irritation as well. By the way, there is nothing wrong with dabbing after voiding rather than wiping.
