I've seen a bizzilion posts on FL and other places that absolutely insist that part of the reason the couple is caging the male is to reduce his size, and it is effective in doing that. Even seen some supposed side by side photos with "evidence" of that.
So I guess I'm wondering from a medical perspective if that's possible.
I've spent as much as 18 months locked, several times. *Apparent* shrinkage was observed after several months of 24/7 with no removal whatsoever. However, this 'shrinkage' was simply a case of the skin having lost some elasticity due to not having had an erection for so long. The erection, when uncaged, caused the skin to stretch very tightly, giving me the somewhat disconcerting feeling that it was about to split open like a cooking sausage does. The skin was also very sensitive, easily chafed/abraded.
The 'condition' resolved itself within a very short time of freedom and being allowed unrestrained erections- days- and 'normal' size was regained. This was tested several times, to ascertain repeatability.
I found that the 'condition' could be avoided completely by the simple expedient of allowing a full, unrestrained erection every week to two weeks (teasing/edging but no orgasm). With a periodic 'stretch' session, skin elasticity can be maintained and no 'loss' of size occurs despite long-term caging.
