Is it vaginismus or is my vagina different?

I already had the physiotherapy treatment, but after a year I still have problems when my partner tries to insert his p, and it hurts. I don't know if it's vaginismus or something completely different. I thought it was because she wasn't aroused and lubricated, but when we change positions and we are well lubricated, she still has a hard time finding my vaginal opening. It is as if it were very small, like a virtual hole that cannot be accessed until you manage to enter a certain dimension, and you have to be very precise to find the exact point to enter. After inserting the head of your penis the pain disappears in a matter of a minute of slow sex. What problem could I have?

I also have to focus on feeling pleasure. If I stop feeling pleasure, I automatically start to feel pain in my vagina.
