Nope, not true. Cuckolding is nothing more than a wife sleeping with other man with the permission of the husband. The cuckold relations that last are the ones where husband and wife communicate a lot, and have each other's best interests in mind. They would never do something what the other doesn't want them to do or the other feels uncomfortable about.Yes it is fine. If you are a true cuckold then you should have no say in the matter anyway.
