Best chastity cage for men with flexible balls?

I’ve been practicing ball stretching for years, and it’s become nearly impossible to find a chastity cage that I can actually remove my penis from. My testicles are quite flexible—they can extend forward by about four inches. Take the CB6000 as an example: when I’m soft, I can shift the device far enough ahead so that pulling out is possible, leaving it secured mainly by my balls. Does anyone have suggestions for a long-term chastity lock that my partner can put on me without this issue?

Another frequent headache with most cages happens during arousal; they tend to get shoved forward by my erect penis, which drags the testicles away from their base and creates pain while still permitting full erection.

The only way to really fix that is getting a PA (perineal arrest).

A PA works as an option, but right now I'm looking for a setup that doesn't need one. Still, thanks for the advice. I am particularly curious about three specific models: the Bird Cage, the Boy Trainer, and this Stainless Steel Chastity Cock Cage ( ... -cage.html). These are currently my top contenders.

I deal with the exact same issue! I can easily slip my shaft out of any cage I've tested, and I'm not keen on getting a PA... Besides, even if I did, it wouldn't fix my main problem. Right now, I have a CB6000S that gets pushed upward during erections, causing painful tugging at the testicles. I've also given the CB3000 and various Birdlocked models (standard and mini) a try. They all share the same flaw: rather than stopping an erection, the rising pressure just pushes the device up until it hurts enough that I take them off. If anyone knows of a solution, please let me know.
