It is generally not appropriate. Such stories are very private and personal. Sharing them may violate the privacy of the relationship and may also make others uncomfortable.
One story could be about a couple who, after a long and tiring day, spontaneously decided to have a romantic evening. They lit candles, put on soft music, and reconnected in a very intimate way. It was special because it was a break from their daily routine and brought them closer.
No. Sexual stories, whether in the context of marriage or not, are private matters. Sharing them publicly is unethical and disrespectful to the individuals involved.
In the vast majority of cases, it's not ethical. When a woman is married, she has made a commitment to her spouse. Any sexual relationship outside of that marriage without proper consent from all parties involved (which is extremely rare and difficult to achieve in a healthy way) is a breach of that commitment. It can also lead to social and family unrest. For example, if there are children in the marriage, such a situation can have a very negative impact on their upbringing and emotional well - being.
Rather than focusing on inappropriate stories like this, we should encourage positive and respectful relationships. Cheating on a marriage through sexual relations with a friend is not something to be glorified or shared in the form of stories.
One good topic is financial management in marriage. Couples need to plan how to earn, save, and spend money together. For example, they can discuss how to save for their children's education or for retirement.
Sharing such stories is inappropriate as they involve private and often intimate aspects of people's relationships. We should respect the privacy and dignity of married couples.
