I'm going to be ordering a jail bird very soon but I'm sure everyone who has ordered one has been in the same boat I am now in, measure once measure twice now unsure weather right or wrong. When flaccid I'm coming it at about 1 1/8 width maybe a little over in one spot and now wondering will this affect comfort in any way has anyone else had this and what did they do.
I followed the sizing intructions on Mature Metal's site. I used the sizing rings and I got a nice snug fit. It sounds like you have the right idea measure several times. You can email them for advice.
I've got many cages plastic and metal but because it's custom theirs always that thought in the back of your mind, the main base ring I know for certain what size I need, I've tried a 1 1/4 ring and that feels okay but doesn't leave any slight indent on the shaft.
If you know the diameter and length of the cages you have you should be able to know if you need 5mm shorter or longer etc. The only thing to watch is some devices hane flat back rings like the cb6000 and many custom cages have round rings. You will need a tighter round steel ring that flat plastic or steel ring
I struggled with the same decision. I ended up ordering the queens keep with the smallest diameter I measured when flaccid. It feels great when it's on but I still wonder if I should have gone up one size only because it seems hard to clean. I went pretty short also, and it seems like everything gets a little wider when pushed back into the shorter cage.
Somebody mentioned the sizing rings, do you have them, if not get them. i ordered mine after getting the rings and sizing. Have been locked in it for three weeks and couldn't be happier with the fit and feel. If you have any questions feel free.
this I bought a chinese clone of the jail bird. ended up i need a 1.87" diameter ring otherwise i get severe problems with night time erections. i had to remove some metal from the ring to get this size but now i know exactly how small i can go before problems arise
I've had more problem with the A-ring/the capture ring than I've had with the length of the cage. Others may say different but that's my situation. The length of the cage hasn't been a problem for me. Just every so often the capture ring/A ring becomes painful but, strangely, not because of nocturnal erections which I've long since learned not to allow. Your mileage may vary.
Along with some others @lockit and @keyheld are both offering you very sound advice hich you would be wise to take on board.
I just got my Queen's Keep and have had it on for 24 hour so far. I followed the sizing recommendations and instructions, and so far it looks like that was the right choice. I went with the standard gap and I have no pinching or discomfort there. For the tube diameter I took their advice to have it snug (but not tight) against the shaft, even though the head is wider (the head needed some mineral oil to slip in). I chose the oval ring, and did take the ring that was the tightest without cutting off blood flow -- the testicles go in ok and i have to really work the shaft into the ring (again, mineral oil). After 24 hours it's feeling more natural. I don't feel constricted in an unhealthy way. So I would listen close to the sizing instructions from MM, and use the sizing rings for your shaft and for the base ring.
