genuinely whats wrong with me

18f, and my vagina has almost never looked like anything i ever see online. theres no hole, theres no clit, theres no like flaps of skin or anything around it. i cannot spread my pussy lips open at all because just the feeling of air on it is so painful. i cant put in a tampon because i genuinely dont know where the hole is, it just feels wrong anywhere i put it, and every vagina i see can just be opened so easily and you just see the clit and the hole but mine looks nothing like that… i can spread my legs completely apart and its just a straight line down to my ass. i’m going to college soon and i want to be able to have sex but i feel like nobody has the same issue as me and i just need to know whats wrong
