Novices and newbies discussion

Chastity is still a new world for me. I’ve tested out multiple cages with mixed results. The CB6000 really bugs me because the tube runs too long for my build, I like having an integrated lock mechanism, and it doesn’t stop me from reaching a full orgasm. Plus, putting it on is a bit of a hassle. Currently, I’m wearing a tiny metal cage that works great for me. The issue arises at night: when I get erections in my sleep, the device gets pushed outward so much that my testicles feel squished and I get a stinging feeling along the underside of my scrotum. It hurts enough to wake me up completely. Would switching to a cage with a longer tube help? That way, it could hold the erection inside without pressing down as hard on my balls?
