How do husband advertise there wfe/gf are available or that they are caged

[Cagedinbrissy]

Women wear a anklet ( some with HW charms) to tell those who understand they are a hot wife and looking.

what is available for men to again tell those who understand there wife/gf is into sharing.

also is there anything a man can wear to say "I'm wearing a cock cage" most people wouldn't know but those in the know can smile as they walk past, better still we could check out there hot wife 

I'm happy to wear something to say I'm caged, if your a bull have a go at picking up my wife
