Vaginal cut? Diagram included

I’ve had this cut like appearance ontop of my clit hood for ages now and it looks better then how it used to be more closed up but still is there (I’ve inserted a diagram for you to see where it’s located) but I only engage in oral I am a virgin and that’s it I have no idea why I have this if it’s normal Bevause the vagina is just a sensitive area and easy to develop cuts? Or scratches? Who else experiences this?
