Chastity device discussions and reviews discussion

I’ve been pondering whether cages with rod constructions, such as the Jailbird or Queen’s Keep (and similar designs where the tube is formed by multiple rods), hinder the process of reaching an orgasm through shaking compared to fully enclosed tube models.

The steel cage I’m currently wearing features a single, solid steel tube. I’ve observed that when erect and shifting the cage back and forth, the interior generates sufficient friction to provide substantial stimulation.

For some time, cages like the Jailbird puzzled me because I assumed their lack of complete enclosure would make stimulating easier. However, upon reflection, I realized that this open structure reduces the surface area against which the penis can rub during movement. So, before deciding on a Jailbird or comparable cage, could someone with experience share how much stimulation they derive from “shaking” or rubbing it back and forth? Is it less than, or more than, what you experienced with a closed tube-style cage?
