One story could be that the shy wife was afraid of the big rooster in the yard because it was so large and noisy. Every time she went near it, it would flap its wings and seem very aggressive.
No, it is not appropriate. Such content involves violating moral and ethical boundaries. We should focus on positive, healthy and respectful relationships in literature and storytelling.
A long time ago, there was a wife who lived on a large estate. There was a big cock that strutted around the yard. The wife would often laugh at the cock's proud gait. One day, the cock found a shiny object and brought it to the wife as if it was a gift. It was a simple pebble but the wife was touched by the cock's gesture.
Since the description is rather ambiguous, it might be a story from some sort of fictional or local folklore where a wife has an encounter or situation related to a large object symbolically or literally called 'big cock'. But without more context, it's hard to say precisely.
No, it's not a common phrase at all. In normal English usage, it seems rather strange and not a typical expression you would hear in everyday conversation or see in general writing.
I don't think so. Usually, in common literature and storytelling, we don't come across such a story often. It could be an out - of - the - ordinary or even inappropriate concept that isn't part of the general narrative we see in most books, movies, etc.
A 'wife shy story' could be a story where a man is shy around his wife, perhaps in social situations or when expressing his feelings. For example, he might be too shy to hold her hand in public or to tell her how much he truly loves her in front of others.
