Chastity and orgasm denial discussion

Hello all, I visit here occasionally, but to be honest, I don’t quite fit in with the crew who wear their cages continuously or for most of the day. It seems impossible for me to keep my device secured. Last night I put it on, and within roughly half an hour, the heat was intense enough that I removed the cage part. I kept the ring on, applied more lotion, and plan to re-lock soon. The issue is that whenever I secure my cage, my left testicle turns a pale red while the veins darken. It’s hard to describe better than that. Urination isn’t an issue, and I can slide most of my pinky through the bottom opening of the ring, confirming blood flow isn’t restricted. Usually, I just tolerate it, but last night the burning sensation became unbearable in 21 minutes so I took it off. Currently, the sore spot is on the rear part of the scrotum, behind the testicles. I keep attempting to wear it longer, yet I suspect my body might not be suited for this kink. Over the past dozen years or so, I’ve used a CB3000, a CB6000, and now the Holy Trainer. Most people advise switching to steel, but I hesitate to spend that much if I can’t wear the plastic Holy Trainer for extended periods; what exactly does steel offer that this one doesn’t? Thanks for reading along with my complaints and rambling about these sensitive areas.
