Im a 17 year old female who's never had sex, but sometime in September I around my vagina started itching. At first I thought it was just irritation from a liner or something so I left it alone, but it didn't heal and it just kept itching/burning. After about a week and a half it went away, but it came back about two weeks later only this time whenever I wiped my skin would bleed and flake off, and when I looked in the mirror there were little cuts that almost look like paper cuts and idk where they came from, what it is, or how to make it stop? I have really bad anxiety and am to scared to tell anyone or go to the doctor and I just wanted to know if anyone could help me out?
