its VPP, its all absolutely normal and looks fine to me, try not to worry and do some research on VPP VESTIBULAR PAPPILOMA. to further re assure you maybe make an appointment with you GU clinic.
I don’t even think its vp, Im 95% sure thats just left over skin from your hymen, it never goes away and people have different shapes and thicknesses, yours was around your vagina instead if a moon shape through it. Do you check yourself regularly?? No need to worry either way, that’s not warts or herpes.
