What Causes Itchy Bumps Between Vagina And Rectum?

Tiny itchy bumps in between vagina and butt. I ve had this for about a week now and it s itchy. It s just small bumps and that s it. No weird color/smelly discharge, no bleeding involved. My pee routine is normal but it burns a little bit. (scale on 1-10. 3) I m a virgin, obviously never been pregnant or had any children, no std s or such. What s going on? (15 year old female.
