Cage feels loose post-shower

Well, I had a shower today that was hotter than usual. My back felt quite tight. When I stepped out, there seemed to be an unusually generous amount of room in the ring holding my cage. I understand how testicles react to heat by hanging lower and rising closer to regulate temperature, but honestly, with minimal effort, I could have likely slipped this thing right off.

At standard operating temperatures, though, the ring seems to fit well—it’s snug without being uncomfortable. I tested a smaller size previously, and it was far too tight, pinching me terribly.

What device are you using?
