Cold Weather Tightening vs Aging

Maybe it’s just me, but this particular winter has my testicles riding much higher and tighter when the temperature drops. It isn’t painful exactly, but uncomfortable enough that I can see them drawn up close. I wake up feeling fine, then start to move in the morning chill and they pull up tight, giving me a ball burn similar to what I felt when I first started wearing chastity devices. I understand temperature shifts cause this tightening. After my shower everything settles down until the next morning. At first I thought it was because I had switched to shorter cages for winter, so I went back to my usual longer cage and confirmed that wasn’t the issue. The evidence suggests that since the weather is typical here and I’m in comfortable cages again, this might just be another effect of aging. What do others think? Mikel
