"The chastity belt" which experts crave never has been used as portrayed in fiction, as the inevitable result would be infections, which would most probably kill the wearer...
The viewpoint have a rather good point, if you take a look at what the manufacturers of today do, in order to make chastity devices, that can be worn, for any longer period of time. The item shown here, would among other things just about eliminate the possibility of defectation.
I'm sorry, that I 'puncture the balloon' like this, but it seems that the task of manufacturing a chastitybelt, which could be worn for more than a few hours ( let alone for years ) IS only a rumor...
