Strange changes happening to my penis

I was usually quite standard when it came to my penis, measuring about three inches soft and nearly seven hard. But as I aged (now a senior) and masturbated more frequently, mine did something I call ‘turtling.’ It retracted inward so that very little remained exposed. This made fitting into the CB6000 much simpler.

After five months without masturbation and only occasional orgasms, my penis has gone back to its normal state, which makes putting on the cage a bit trickier now. Has anyone else had this kind of change or something alike? My wife is happy with it since I’m hanging out again like before.
