Are the slits normal?

Ive never really thought about it until recently when I started to become sexually active, it is very painful when I am touched above the vaginal opening (everything that's highlighted in black) Its a burning stinging sort of pain and I've never figured it out, its been this way since I was a child. I've been assuming its a vaginal abnormality with no cure but I would like to know more about it. It was always painful, I would go days peeing in pain (UTI) if soap were ever to touch that area. It I touch the area while it's covered by the labia it doesn't hurt though.
