Well, it might be a rather vulgar concept, but if we look at it from a storytelling perspective, it could be used to explore the idea of unexpected changes in relationships. Maybe it shows how external factors, symbolized by the 'bigger cock' in this rather crass way, can disrupt a seemingly stable marriage. It could also be a way to shock the reader and make them think about the fragility of relationships in general.
We could rewrite it as a story about a wife finding a more positive and fulfilling connection with someone who has a bigger heart. So instead of focusing on a vulgar aspect, it becomes about emotional depth.
Using such expressions is not acceptable in civilized conversation. We can talk about things like building good relationships, mutual respect in marriage, etc.
If 'bigger cock' is misinterpreted in an inappropriate way, we should avoid such topics. Instead, let's talk about a story of a big clock. There was an old grandfather clock in a small town's square. It was huge and had been there for generations. People in the town would gather around it during special events, and it chimed melodiously at every hour, marking the passage of time for the whole community.
A possible 'bigger cock story' could be about a cockerel that won a competition for the largest and most beautiful in a county fair. It had a huge comb and long, shiny feathers that made it stand out among all the other entries.
No. Comparing in such a vulgar way is inappropriate and not acceptable in a civilized society. We should focus on positive, respectful and ethical topics.
