Which tube length?

I did not condemn anything I passed on information from a chastity device manufacturer, I passed this on to help the OP to decide.
I am wearing a jailbird that is a perfect fit.
My information comes from my own experience and tried and tested advice from Mature Metal.

Maybe it's you who should not give advice on something you have not tried.
Hands on beads hearsay every time.

I did not come here for a pissing contest. I have passed on information I think will be useful.
With this information and that from other posts I hope the op gets a perfect fitting device.

 

@lockit Unlike you I am unable to experience the singular wearing a device first hand.
However, I have spoken with, recommended devices for, received detailed and lengthy feedback from and coached many locked submissives over the last ten years both in and outside this forum.
Does that experience really amount to nothing?.
Is there really any need for you to be rude?.

 

My thoughts on this are that some of the short tubes are little more than an end-cap attached to a base ring. Extend that logic only a bit further and you have a base ring with a flat plate across it. It might stop the penis emerging much outside the body but that is all.

 

yes and as well the teeny tiny ones are very very comfy. but i don't spose that a big man cud have one.

 

I am about 7cm when soft and wear a 4cm cage it is as Mascara Snake says the most comfortable arrangement as the penis in a short cage cannot grow sufficiently large to cause any significant forward pressure so the ball sack is more comfortable.
Also consider wearing a urethral insert too as this helps keep the penis smaller.
In a 4cm cage you never experience any erection at all just a little swelling
I started out in a CB6000 then CB6000S then stainless until realising that smaller is better.

Anyway check out my photos's there's plenty to see what I mean.

not meant bad, but this is a bit like asking for the size of your shoes! You will be outnumbered by advices, all meant well and given due to personal experiences, but in the end I'm afraid to tell: you're the only one to know after you tried...
