If you're uncomfortable, you should communicate your discomfort clearly. Say something like 'Honey, I don't think these stories are appropriate for us to share right now.'
First of all, don't overreact. Have an open and honest conversation with her. Let her know how you feel about it. You can say something like 'Honey, I love our conversations, but these kinds of dirty stories make me a bit uneasy. I think we should focus more on positive and family - friendly topics.' Then, you can start a new conversation about a more suitable topic to shift the mood in a positive direction.
It might not be typical. Usually, such stories are considered very private. However, if she has a really open relationship with you and she's just trying to be more communicative about certain aspects of relationships in general, it could be okay. But still, it's a bit odd.
In general society, this is not acceptable behavior. Social norms dictate that sexual matters are private. If a wife tells such stories, it could be seen as inappropriate or disrespectful. However, in the context of a very open - minded and private relationship where boundaries have been clearly defined between the couple, it might be a different story. But still, it's not something that should be done casually or without considering the potential impact on others.
It depends on the relationship between the couple. In a very open and consensual relationship where both partners are comfortable with this kind of communication, it might be okay within the privacy of their relationship. But generally speaking, it goes against common propriety.
Another alternative could be stories about the adventures or challenges a married couple faces together. This can include things like starting a new business together, traveling to new places, or overcoming difficulties in their relationship through mutual support and understanding.
First, it's important to stay calm. Then, have an open conversation about your values and how this behavior makes you feel. You might say 'I respect our relationship and think we should keep our communication clean and respectful. These stories are not in line with that.' It's about setting boundaries in a relationship in a non - confrontational way.
