I am a cuckold husband
As we live in India it is not easy to open up about cuckolding because of social stigma. I personally love to tell everyone that I am a happy cuck but my wife is strictly controlling my urge to go open.
Other than her lovers only two of her close female friends are aware of our cuckolding relationship.
You need to be very careful when you engage with others to make sure the encounters are private. There is no harm in opening up about your relationship if the other person is really trustworthy. But never give them any material evidences which could lead to unnecessary issues.
But just in case someone gets to know without your intention, don't panic. Cuckolding is your private matter and it is not illegal. You don't need to get scared. If any third person ever questions you about it, be confident and make them aware of their boundaries. They don't have any role to intervene in your private matters.
