How many cuckold relationships begin because the wife was secretly having sex on the side and got found out?
It seems to me that cuckoldry is a topic that most don't seem capable/prepared to bring up in conversation within a marriage, whereas affairs are common. So maybe for a lot of marriages, this is how it starts.
What is your experience? And did you have to go through a period of emotional distress at finding out about what she was up to? If so, how did you get passed it?
