From a psychological perspective, if we assume such a situation in a story, it could potentially point to issues of sexual dissatisfaction within a relationship. It might suggest that the wife is seeking more sexual stimulation or a different kind of sexual experience. However, this is a very simplistic view and in reality, many factors could contribute to such a statement in a fictional context, such as power dynamics or the exploration of sexual fantasies.
If she means stories about roosters, you could simply start telling her about the time you saw a really colorful rooster at a fair. Just keep it light and fun.
This phrase is quite ambiguous. It might be misinterpreted as something improper. But if we consider 'cock' in the sense of a male chicken, it could mean she has an interest in stories about them. Maybe she grew up on a farm or just has a strange fascination with chicken - related tales. For example, stories about a rooster that wakes up the whole village every morning could be what she's interested in.
Well, in the world of literature, you don't often find such a blatant theme. There are so many other aspects of human relationships to explore. For example, love, trust, and communication between a husband and a wife are far more important and commonly written about. This kind of theme is more likely to be found in very specific, perhaps less - respected types of writing.
Using such expressions is not acceptable in civilized conversation. We can talk about things like building good relationships, mutual respect in marriage, etc.
