I just started wearing a device with my wife as kh and have some questions. I got a metal "Jailhouse" device which looks like the jailbird but with metal rings instead of horizontal bars. I think I will get a custom. One from MM eventually.
First, can wearing a device like this cause any long term physical damage?
How should the ring fit? I've tried the 1.5, 1.75 and 2" rings. The 1.5 fits the most snug but the 1.75 and 2" rings are more comfy. The bigger rings will slide down my shaft though. I can barely get my index finger under the smallest ring just up to the first knuckle. Once I get in the device I have just under .5" of space until the tip of the device. Is that too big? With the 1.75 or 2" ring I would wake up at night with a burning feeling at the base of my scrotum where the ring is.
While wearing the device with the smallest ring I decided to watch some porn. Holy shit! It was painful. My cock and balls killed as i got hard. I had to turn the porn off. Teaches me

I also want to try wearing a strap on harness while locked up and fuck my wife with a big black cock attached to the harness. Anyone else done that or can recommend a good harness for men?
