Cheap anti-pullout solution

I discovered a cheap effective way to add a retainer ring to many cage style devices. I have always had trouble with cages because aside from constant comfort issues (I've tried multiple real Holy Trainers among other popular devices) I find that pullout is extremely easy. I know piercing is very effective as are tether spouts and it seems people have had good success with retainer rings but I have never had the chance to try one. I found that a set of ring sizers (for jewelry) could provide a good solution. These sets can be found on Amazon for as little as $5. I picked up a set that sizes up to 15 ring size and after trying several I found the 13.5 sizer worked best for me. The rings have a small loop attached to them which can be passed through the cage to a secondary lock. It is important when using a retainer that it is attached at the bottom not the top of the cage as this allows the ring to stay hooked around the penis head making pullout nearly impossible. I have been testing this setup for several days and I absolutely cannot pullout, so I can say for the first time I don't need my Neosteel all the time to remain chaste. I used a very cheap cage to try this out, but this idea should work on many cages.

Here's what I used to make this work, other parts may work as well just sharing exactly what I did. These ring sizers do get very small, use discretion before trying to go too small with these. The smallest I tried was 13 and I don't think I'd want to try anything smaller. The other thing I did was sand down the edges of the luggage lock after finding the sharp corners caused some discomfort, its fairly soft brass so I was able to do this with regular 400 grit sandpaper.

Brinks Luggage locks (note that some luggage locks have thicker shackles and will not pass through the sizer loop)

Fancalen cage (this cage also happens to be very comfortable for me, where Holy Trainers and others were not)

Also, if you want an actually secure lock, I highly recommend the Burg Wachter ME/2. The cheap locks that come with generic cages can be opened with a paper clip or any key remotely similar to what came with it.

Here's the parts and what it looks like assembled. To install the device, first I put the cage ring around my testicles like normal when installing a cage. Then I place the ring sizer around the frenum and place it into the cage, I lock the ring sizer with the luggage lock before locking the cage to its ring.

 

I no longer use this solution as I use my Neosteel exclusively now. This was an ok temporary solution but I did end up finding a way out of it. I am sure there is a risk if you use too small a ring and there is too much swelling.
