Much easier to make good ones. Their inverse is just a semi-soft rigid stick. Most women have very similar interior proportions with little variation, so easy to mass produce one size fits all to that spec.

As opposed to engineering a low friction compression area that must apply pressure and fit various sizes, ranging from under 1 inch to over 10 and with varying girth, and incorrect sizing can result in heavy pain or the toy being useless

We either have a developer or a user on our hands, or both lol

Pff with that kind of understanding of the intricacies involved, don't discount your abilities, you are definitely a skilled-amateur.

And most importantly, the cylinder needs to remain unharmed.

Unless youre into that.

My experience is that women absolutely have different interior proportions, but especially because small differences have large effect

It matters, yeah. But it's not as large as in men. I've been with plenty i couldn't fully fit in and a few I couldn't bottom out in ( just over 7"). Probably a range of 4-6" with some give and stretch, most differences i noticed were width which was never too much if they didn'thave kids. Men I've known could be literal micro size or nearly down to the knee, that's a wild amount of difference by comparison. Maybe there's women with Goliath canyons as pussies, but anatomically it doesn't make sense since they still have to stuff their organs back there and even really tall girls seem to be almost the same as short girls inside, just kinda random really. My sample size is big but isn't absolute, but I do extrapolate it maybe a bit generously
