hi pls help a gal out!!!

i started masturbating a while ago and i can fit like 3 or 4 fingers in, but my viabrator doesn’t fit comfortably and it only goes in if i’m in a certain position!!

i also can’t tell if my hymen is still intact or not and my urethra is like super low. i just feel like my vagina is completely different to any diagrams i’ve seen and my opening is at the very very bottom. i’ve also got a chunk of skin that moves into my opening if i masturbate, and i’m not sure if that’s normal because it’s way too thick to be my hymen?

is this normal? what do i do, should i go see my doctor??

ANY ANSWER IS APPRECIATED ❤️❤️
