Cold Testicles with the CB6000s

I’ve recently acquired a CB6000s and experimented with various configurations of spacers and base rings. I discovered that the largest base ring included in the cage, paired with the second-largest spacer, offered an excellent mix of comfort, snugness, security, and some looseness. However, after just a few minutes, my balls become cold even when flaccid. They don’t change color; they simply feel cool to the touch. I suspected the base ring might be slightly too small. Since it was the largest one provided with the chastity device, I ordered extra-large rings from the manufacturer. Even so, for any ring that doesn’t allow my genitals to slip through easily, my balls get cold. With the largest spacer used, my balls tend to slide right between the base ring and the cage.

I was eager to wear this chastity belt for extended periods, but after reading up on it here and elsewhere, I’m a bit concerned that this coolness might have long-term effects on my testicles.

My scrotum is relatively small with high-hanging balls, and about ten years ago, I had surgery to correct an undescended left testicle. Could these factors be why the CB6000s doesn’t fit me comfortably? Also, I’m interested in the Holy Trainer v2 Mini; would that device present similar issues?

Ask for an egg cosy for Christmas.;-) That will keep them as warm as toast... Seriously though, is this your first device overall or just your first CB6000S? You'll likely find that your balls get a bit cool at the start anyway, but I expect they’ll perk up and warm back up after about a day. That was my experience.
