The vagina is a muscular canal.

It's this elastic fibromuscular tube, and it's made of entirely smooth muscle tissue.

That muscle is what connects the cervix to the outside of the body.

Yeah, for sure.

But size changes before penetration.

So during arousal, the vagina goes through a normal physiological process called tenting, where the vaginal canal lengthens and widens.

It relaxes and lubricates.

Or just never turn somebody on.

Right.

Oh, no.

He should get an award that's comedy gold.

Yeah, I mean, it's amazing.

And the vagina is highly elastic.

And it can double in length from around three inches to up to seven inches.

So increased blood flow causes the tissue to expand and relax, which increases the flexibility.

And then the width expands too.

So the vaginal walls, which are folded and also highly elastic,

expands significantly in width to accommodate penetration from a narrow resting size to about two to three inches in diameter during arousal.

So the increased blood flow also causes the walls to secrete lubricating fluid, which reduces friction.

I mean, it's wild.
