I often wonder about who else is locked up when I'm out and about.

I agree that if you study the woman and see how dominant she appears, it's a pretty good sign the guy is caged. My wife is a business leader in our town. She is confident, demanding, outspoken, assertive, all that. She mingles with politicians.

I am soft spoken and stay in her shadow. She does tell people that I am a good housewife. I bet guys like the ones inquiring about caging here would have to think someone like me is indeed caged, and they would be correct.

So, my point is .... check out the woman and her actions.
 
5% of men have an interest in chastity (not necessarily as their main fetish though). 1% of men are regularly wearing a cage.

as a statistician I can tell you that in order for those percentages to be significantly reliable, you'd need to have that dream 24 times.
