vaginal penetration is uncomfortable and scary

18F here, i’ve always been trying to find the entrance of my vagina, but it always feels really uncomfortable when i put my fingers in, even when im relaxed. So when i feel the inside of my vagina, the middle of it seems to be a “meat wall” whereas there is a slit or opening on the far left but it doesn’t feel good but rather uncomfortable when i put my fingers in. does anyone else have the same problem? should i get it checked? I’m honestly so scared now because my boyfriend has been telling me he wants to have sex with me for a long time and i told him i want it too, and now it seems like i would just be suffering through the whole thing.
