Soemthing wrong with vaginal anatomy

I recently started adding fingering to my masturbation routine and I noticed a few things about my vagina (I’ve only ever put my fingers inside my own so idk if this is normal). When I first put it in a little past the opening, I feel like I kinda have to wiggle my finger a bit to get it in the canal. Like I have to kinda push some of the opening down to get it into the canal.

When I add two fingers, the skin surrounding the opening feels tight on my fingers (not in a bad way so that it hurts, I can just feel the skin surround my fingers).

Once they’re in I feel like they take a “c” shape because that’s the only shape they can take.

I’ve only had sex twice and it was a little uncomfortable (if that matters).

Is this normal or is there something wrong with my anatomy
