You are exactly right, if you stopped 100 average women on the street and showed them a metal chastity cage and asked them what they think it is they would probably think a medieval torture device, like something they would have in Game Of Thrones to torture their worst enemy! Look at womens sex toys, they look smooth, clean and colourful. Metal and barbaric does not fit the bill, unless you are into BDSM. I would guess most members of this site are into BDSM in some way, so maybe you cannot see it from the point of view of someone who is outside of that scene. Imagine if devices did look more like this they would probably fly off the shelves in Ann Summers stores. The reason I am thinking of all this is because of all the "How can I get my wife interested in chastity?" threads. If a wife has an interest in BDSM she'll be open minded to the traditional devices, if she doesn't, then this is a good way to pique her interest.
