Interesting, and thank you. I am an Asian lady and never heard of it but not Chinese so who knows. Is your wife Chinese'? Does it work or has it worked for you in the past? I bet she is proud of you willing to display yourself as a cuckold!it is an old tradition in China, if you wear one is because your wife cheats on you. But as almost every tradition is coming to this side of the world and it has become a I AM A CUCK sign for the hubby. Hope to find one who knows it.
