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.
Yes, it is clearly an inappropriate interest. Such a topic is private and should not be a subject of interest among people in this relationship. It violates the normal boundaries of friendship and marriage.
You might also need to have an open conversation with your wife. Explain the situation to her without causing unnecessary misunderstandings. Maybe she can help handle this delicate situation. For instance, she could talk to her friend and make it clear that such behavior is not proper in the context of your relationship.
Well, first of all, it's important to note that 'cock stories' are not something that should be part of a normal or healthy relationship conversation. You could tell your wife that this kind of talk is not acceptable in your relationship. Then, try to find out if there's a deeper reason behind her request, like if she's heard something strange lately or if she's just joking in a very wrong way. Explain to her that you want to focus on positive and respectful communication.
This is an extremely inappropriate situation. Our bodies are private, and sharing or showing private parts in such a context is not only against basic social ethics but can also lead to uncomfortable and potentially harmful situations. Friends, whether male or female, should respect each other's privacy and not make such improper requests. If faced with such a situation, it is necessary to communicate clearly that this is unacceptable behavior.
I'm not entirely sure what this specific phrase means. It could potentially be a very unclear or made - up statement. It might be a case of some local or personal jargon that needs more context to be accurately defined.
This is completely inappropriate behavior. Such topics involve vulgar and unethical content that goes against moral and social norms. We should abide by proper values and respect boundaries in family relationships and society.
