how do virgins have their mothly period if the hymen block the birth canal?

Answer 1

The hymen only partially covers the vagina - it's as simple as that!

Answer 2

In most women, the hymen only partially covers the opening to the vagina. However, in some small cases, there is what is called an imperforated hymen. In those caes ,the hymen completely covers the entrance to the vagina.

In those cases, the pediatrician will usually note that at birth or upon a very early examination, and at a time well before menstruation begins, they will make a small opening in the hymen.

Answer 3

Because it doesn't entirely block it, for one thing, and because it rarely survives childhood anyway. There are lots of things besides sexual intercourse that can render a hymen broken or stretched. And some girls never have them at all. Some very few have ones that are thick and not broken, and a doctor has to break it with a surgical instrument to allow the blood to flow. That condition is pretty rare.

Virginity is about a specific act of penetration, and not about whether the girl has ever needed to use a tampon or otherwise have something inserted in her vagina. It's a spiritual condition, not a medical one!

Answer 4

It's a myth that it completely covers the opening. Some girls don't even have one, or it gets torn by other things besides sex early on in life (sports activities, etc.)
