Is my device fitted correctly?

smaller ring.

 

Good way to tell is to stick your finger between the ring and scrotum. If you can just about get the finger tip under it, that is a good fit. If you can get most of the finger under it, ring is too large. The ring will tend to migrate south. If my penis tries to get hard it will pull the whole device away from my body and the ring will go as far down my scrotum as it can until my testicles stop it. If you are hung low and loose, it will migrate south. as it did with all 5 of my devices.

 

Now I'm thinking that my base ring may be a little too big too, saw some on dhgate , but I'm not sure if I should just get it 2mm smaller or four. I have a 40mm now. But sometimes my balls shrink back and pull out through the small space between the ring and the cage, I hate when that happens.
When I got the cage from dhgate there was three choices , but when I looked today I saw they had 8 different size rings for about 17$ almost what I paid for the whole thing there.

 

I'd vote smaller ring as well. A few mm makes a huge dif, no pun intended lol

 

I got the new base ring today, and the 2mm is quite a bit smaller, it was hard to get on, maybe partly because I had been swinging free for the past few days. It was burning a bit at first, I used some Neosporin , it helps maybe better than Vaseline. I don't think I will slip out of this ring like the other one. I've had it on for about 12 hours.
