Well, knowing the average diameter and depth you know the volume and hence the size. so really, you should state you vagina size in volumetric units like mL or fluid ounces
Some reasearchers have studied the size of the vagina by volume, but they took a casting. It is hard to fill the vagina with a liquid, without it just squirting back out of the opening before any pressure has been put on the walls of the vagina. Really, depth is the only measurement that is easily taken, other than researchers making castings with special materials.
I googled this and found nothing. I wanna see a picture of a vagina casting. Anyone have a link? I did see the personal vulva casting kit for a refridgerator magnet however. And i'm gonna surprise my old lady at her 50th birthday party with one!
Hi lostminty, I think your question is good one. I guess I can take more in girth-wise than lengthwise. I have had two boyfriends with very long penises. One man had 10 inches, and my current boyfriend has 8 inches. It hurts when they would go in all the way. It actually felt like I was being opened up again for the first time, which is kind of exciting. I've never had anyone say I was too big, or not tight enough. I think I might be about 6 inches deep. But when I am extremely turned on, and the man takes his time, I slowly open up and can fit it all the way in and not have it hurt, and then the pain turns to pleasure and it feels really good.
