Vagina size

Im curious right because my friends tell me they can only get one finger in which gives me “pick me” energy as i can get 2 in even when im unaroused.

I do kegals and hold them the whole time when i have sex cause im paranoid its not tight enough, im really skinny and it feels boney lmao but im just wondering can vaginas be bigger/smaller than other? Im not on about ‘vaginas cant get loose’, but rather if people are naturally wider/ smaller

Im so self conscious ever since a guy that had a fairly small dick said i was loose :(
