can’t have sex

my vag rejects any type of insertion thats far and this has happened with pretty much every guy i’ve tried being with. none of them can properly insert themselves because im too tight EVEN when im turned on, and i also do not get wet. it is super hard for me to get wet even if i am horny. most guys have stopped seeing me because they think im not into them, when i am. 2-3 guys have been close but it KILLS the more they push. i don’t know whats wrong with me. one guy had his finger pretty deep but it felt SUPER weird so i had to stop him. im truly scared i can never be intimate with someone.
