Talk to Gynecologist on Impossible Sex

So my wife has a "problem" with her vaginal opening, the pubic bone is protruding into her vagina and pushing her urethra into her vagina, making any penetration, even sometime my finger painful. we tried all types of things, lubes, wideners (4 sizes and we were only able to put the first 2, the third was impossible)., 2 sizes of plastic Speculums, (only the small was successful and only into the first step and it was very painful), we even got an anal balloon (and i was barely able to enter).

my wife has an issue with other people touching her, she did visit a gyneco locally, but it was a generic answer: all is normal, apply lube and use wideners.

i made a couple of pictures on photoshop to explain what is most likely her case (since we only got my finger to try to figure out what is happening inside)

The pubic bone is pushing the urethra to the vaginal opening, it can be felt without pushing upwards at all

what can be the solution? other than trying lubes, ludo
