Tiny cuts in vulva?

Sonya

This is a little embarrassing, but it’s a serious question. I have had little cuts in my vulva for a while now, and I was wondering if anyone knew what was causing them?

The cuts are where the labia majora start all the way at the top, right in the folds.

It doesn’t bother me that much but causes discomfort sometimes.
