No, it is not appropriate. Such topics involve private and often inappropriate aspects of a relationship. Everyone has the right to privacy and respect in their relationships, and sharing such stories without consent is unethical.
Definitely not. These kinds of stories violate the boundaries of privacy and respect. A healthy relationship is built on mutual understanding and respect, and spreading such stories goes against those principles. Moreover, it can make others uncomfortable and is not suitable for public discussion.
It's completely inappropriate. Relationships are complex and private matters. A story about a 'wife can't say no sex' is not only disrespectful to the individual involved but also goes against the norms of a respectful and consensual relationship. We should focus on positive and respectful aspects of relationships rather than such inappropriate topics.
