I'm not sure what to think about it, there is a barrier on the inside of my vagina, I'm a virgin so I was pretty sure it was hymen but it completely covers my hole, except for a very very small part at the bottom of my entrence. I googled imperforated hymen and it doesn't really look like that, it has that wall and a small puckered part of skin in the middle of he wall, not sure what to do and I'm not really comfortable to go to a gyno or talking to my mother about it
wat u are explaining is normal and your hymen
the reason theres a small hole in it is to allow mestrual blood to exit the vagina also its quite stretchy so allows u to insert tampons etc
an intact normal hymen covers the entrance to the vagina but has a small exit hole so dont be concerned its very normal
Bless you hahaha
