So after experimenting with a Holy Trainer for a bit, about 18 months ago, I took the plunge and ordered a MCN Contender. Super quick delivery and awesome craftsman ship. It fit so well that it was scary! After a test drive, I had Mark make a few minor changes to the PA Hook and I honed the base ring to flatten the inside and make it slightly larger ID. It became a cage that I could be kept in indefinitely. My beautiful wife does not keep me locked all the time, but does like me caged on the weekends and anytime that I am home alone. She uses me for PIV about twice a week, if she choses. The Contender has worked very well until just recently, the last several times that I have been locked for several days, I have developed a small edema on either the shaft (neck) near the glands or on the corona of the glands. Remove cage and a few hours later the edema disappears. Not sure what has changed. Too short? Too short? Too Tight? My body composition, weight, and health have not changed, just a little older. Any thoughts? We are planning an extended lock down in December and I would like to get this right before then
What diameter is your cage, and does your penis touch the cage walls when flaccid? Ideally there should be a small bit of space between your penis and the cage rings, to prevent fluids from being trapped If this isn't the problem then something else is causing fluid retention, and other variables need to be eliminated.
That's exactly the problem I had with a plastic cage (The Vice). I have ordered the larger tube. Here is the original tube - the tube goes from 36mm to 34mm at the head. Although the squeezing feeling was very pleasurable, it's unsustainable for longer term use.
Update On Edema Issue! So after thinking about this minor edema issue for a bit, I decided to increase the inside diameter of the cage rings that ride on the back side of the corona glands (head) and on the back of the shaft (two ring cage). I honed and flattened the inside of both rings, which increased the inside diameter about 0.025 to 0.030. The flattening of the inside reduces the pressure point by increasing the surface area and the slight increase in inside diameter seem to have resolved the issue. A good polish with 400 & 600 grit and we are locked up again!
