I'm sorry that that upset you. I completely understand why you're feeling so frustrated.
If it makes you feel any better, I do think that this might have resulted in some useful information.
I have a feeling -- I can't say for sure, alas, but a lot of what you have posted so far seems to support it -- that you might just be someone whose hymen hasn't worn away as much as it more often does for people by now or that has a formation (there are so many different ways they wear away) that allows for some menstrual flow and other fluids to get through, but doesn't have any one opening big enough for your finger to slide through that tissue yet. I am thinking that might be what feels like a wall for you.
If that's the case, then you have a couple options: 1) you can just let that be and know it'll still probably gradually wear away over a lifetime as it most often does for people, and that if and when you engage in any kind of sexual activity that involves the vagina in any way -- that can be fingers or other body parts, toys, etc. -- that will probably speed up that process, and/or b) once we're all done sheltering in place and healthcare systems are working a bit more normally, you can go and see a sexual healthcare provider and let them take a look. In the event I'm right, they can offer you some options if you want to change this. You don't have to, again, but if you want to, there are some healthcare options for that.
Alternately, I think this may just be a matter of your expectations for what should happen not matching reality. It's not so easy to show some of these things in words, but when I said "womb of requirement" wasn't off, I meant it: by and large, when nothing is inside the vagina, it really IS mostly a closed orifice and can be difficult to see. That's really common. It's not super common for it to just look like an open crevice or hole so much as some folds (though even "folds" isn't the best description) of tissue both surrounding and covering that opening. In this case, that "wall" you are hitting is most likely just the back of the vaginal canal, because often when we try and put our own fingers in, a lot of angles we do that at have us pushing backwards against the vaginal canal rather than up and into it, because that canal isn't straight back from the opening in many ways we'll be sitting, but instead, kind of back and up at about a 30-40 degree angle.
How do you feel about all of that?
