Getting it on and keeping it on

When I went from 50 to 45 I had and have a tough time getting the ring on, and it’s a solid ring. Once I got it on I have no problem with escape. Once your ring is on you should be able to fit a finger between ring and body. Any more than that I would suspect ring is too big.
As for difficulties getting the second ball through
I’m with you there. I kinda cup the ball with my hand pressed into my groun to cut off the ball’s escape route and kinda push the ball through and push the ring over and it basically pops in, then feed the shaft through. Now everyone’s anatomy is different but if you’re having such a tough time getting a 50 on and then having it slip out so quickly you may need to go to a hinged 45
My original 50 wasn’t the easiest to get on and I only went to a 45 by an ordering error so I struggled to get it on and that was the best mistake I made! Good luck

 

To prevent your balls from retracting into the body while you try to put the ring on, you can use a rope ir shoelace to tie it like a cockring don't be afraid and do it tight...
Pull your balls one after each other, add the tube and lock. Remove the rope.

I did it several times... don't need anymore but I keep a string of rope handy just in case...

For the ball slip... two main factors... ring suze and the gap... you metal cage might have a bigger gap than the one used on your cb...

 

I had a very similar issue. After much advice I bought a plastic cage with a 45mm ring and the cage pulls on to my balls.

Also a tip I have found for getting my balls through the ring without them escaping is to tie them with an old shoe lace. The lace can be pulled out once the cage is on.

 

Practice.

Also a hot shower first, or whatever works for you to get things relaxed down there, with your scrotal skin as loose as possible.

I found that laying on my back worked too, when I was initially trying to fit into a small ring. You can’t see what you’re doing but you can go by feel.

Also try changing which nut you slip in first. One is likely slightly larger than the other and it will be easiest if that one goes through first.

If you try again with the shoelace, the way I would do it is: tie it around your sack initially, then pull as much skin through (away from you) as you can comfortably can, then tighten the shoelace. Repeat until ideally you have the lace very tight and your balls are sitting fairly loosely in your sac. Looseness really helps, so if you’re high and tight this will be your biggest challenge. That’s where getting things warm, and keeping them that way, helps.

You could also try tying the shoelace so it only traps your balls rather than going around your shaft as well. That might help cut off their escape route.

Good luck and don’t give up!

 

I find that using lotion helps slide everything through, especially if the ring is properly sized and not too large.

 

The ring should be snug but too not tight. You should be able to get the tip of your finger between the ring and your body. As for getting everything in there, it's easiest if you are warm and relaxed. With the cooler weather your guys will want to hide and at least for me, it doesn't have to be that much cooler. Hold the ring up against your scrotum and pull as much of your scrotum through as you comfortably can. Push one testicle through and then the other. If the one in the ring wants to slide back out as you hunt down the other, you may have to try and hold him in place (just pulling gently on the scrotum may help). The natural fear is pain, try to push with two fingers or your thumb and first two fingers to help guide the testicle and spread out the force of pushing.

For me I've found that getting my penis through the ring as quickly as possible after the boys helps a lot. I typically lube the ring and rub whatever if left on my finger (or maybe a little more) around the edge of my genitals, I also lightly lube the head of my penis, just because it makes pushing it through a little easier. I try to "prep" everything before starting. Once everything is inside, pull on your scrotum and penis to adjust. Then install the tube.

What keeps in you in is called "gap" and it's a three dimensional space created by the the area of the ring less the area of the tube plus the space between the base ring and the back of the tube. Custom makes are able able to adjust the angle of the tube, increasing or decreasing the gap. The Chinese makers never mention gap, nor it is adjustable on most devices. So that pretty much leave picking smaller ring or larger tube. Unfortunately most of the Chinese ring sizes jump 5mm from 50mm to 45mm, which may be too much. That either means custom or asking one of the Chinese sellers if they can get you, say, a 48mm ring. Some do advertise "customization" but I have never inquired.

 

I have Chinese devices; I found they stay secured if I attach them to a steel waist belt to the ring. This tends to pull the device up and back to your body. Additionally, I have modified the devices for better comfort; use a rotary tool and very fine sand paper to round edges.

 

Thanks for sharing! As for the explicit photo, I think proper forum etiquette is to warn users than NSFW picture is coming. Warning, several carriage returns to create a space and then the pic.

From this angle everything looks good and from what you describe the fit of the base ring sounds correct. Genitals are like snowflakes, no two are identical. As I said before, if you continue to escape then it's probably and issue with the angle between the back of the tube and the base ring. Unfortunately there isn't much you can do to adjust that. If you can find one, you could try a slightly smaller base ring (~48mm).
