It's difficult to say how common they are. In today's society, with so many distractions and opportunities for people to interact outside of their marriages, there may be more instances than in the past. But still, a large number of marriages are based on loyalty and commitment, so while it does occur, it might not be the norm. There are also cultural factors at play. In some cultures, any behavior that could lead to a husband feeling cuckolded is highly frowned upon and less likely to happen openly.

It's not common at all. Normal stories usually revolve around love, friendship, adventure, etc. The idea of a 'school for cuckolds' is so specific and somewhat controversial that it's not likely to be a widespread story type.
