They talk about pinching during insertion... yet how does it not pinch settling on flesh then being pulled back out?
I think I can answer that, the difference is pushing vs. pulling. As you work each individual link in, it's moving independantly of the prior link, perhaps catching some tissue inbetween. As you draw it out, each link is already pulling on the next, voila!
(Although I haven't tried a chain, I've inserted a container of marbles vaginally and anally one-by-one. Working the vaginal muscles to eject marbles is a good excercise in control.)
Enjoy,

PS: Used a plastic food storage bag anally to 'contain' the marbles.
