It doesn't make sense now that I've stopped to think about it. Penii come in a lot of different shapes right? Why would a guy who's thicker at the base or closer to the head measure mid shaft? Does a woman not feel girth if it's not in the middle?:biggrin1: Now if it's true that most of the nerve endings in the vagina are closer to the opening I would think it would make sense for that to be the default spot to start measuring. Or maybe it makes the most sense to just measure where it's the thickest.
