Vagina makes the world go round. Cishet men come out of it, spend all their lives trying to get back into it. Women have it, and for some it’s the gift that keeps on giving; the never maxed-out ATM card. But do you ever get the sense that you don’t know too much…or even anything about it?
Like, at your big age, you still don’t know what the Vulva is.
You probably mean “Vulva” whenever you say “Vagina”
The Vulva basically refers everything you look at when you look down there. Vagina proper is actually the hole which everything happens in. That “hole” is where the penis (or fingers, let’s not forget the fingers. Very very important) is usually inserted.
Also, babies pass there.
….which brings us to our next point.
The Vagina Is Expandable
The vagina has the ability to stretch to accommodate a whole baby. It has no problem with a penis. For some women, the depth from the vaginal opening to the tip of the cervix is 3 to 4 inches when they are not sexually aroused. Other women may have a vaginal depth of five to seven inches. So you have to come correct.
This is the science of it though. When your girl’s body comes, blood flows to her genital area, and the resulting sexual excitement causes the upper two-thirds of the vagina to lengthen by forcing the cervix and uterus to ascend. Then she becomes wet, because the vagina lubricates itself to await easy penetration.
So you can think of the vaginal canal as if it were a balloon that is not filled with any air. The walls, which have the potential to expand and elongate, gently touch one another. When something is placed inside, they mold around the width and accommodate the length of a penis, tampon, finger/fingers, or sex toy.
