Well, it's important to handle it delicately. Firstly, don't use it as ammunition to start an argument. Instead, see it as an opportunity to understand her deeper feelings or desires perhaps. But also, since she was drunk, it might be wise to take it with a grain of salt and approach the topic again when she's fully in control of her faculties to get a more accurate understanding.
Just listen attentively. Nod and show that you're interested in what she's saying.
Well, it's a complex matter. In general, confessions made while drunk might not be fully reliable as the person's judgment is impaired. Ethically, if these confessions are private and not used to harm or manipulate the wife later, it could be considered a matter between a couple. But if shared without consent, it becomes unethical.
Tell her that it makes you uncomfortable and that it might also make others uncomfortable. Suggest finding other topics to talk about that are more appropriate for public or general conversation. You might say, 'I love you, but sharing sex stories is not something I'm okay with. Let's talk about our travels or hobbies instead.'
If you're comfortable with it, you can listen with an open mind and maybe even share your own thoughts. But if it makes you uncomfortable, calmly tell her how you feel.
Politely but firmly ask her to stop. For example, you could say 'This is not the right time or place for such stories.'
One should firmly and clearly express that such talk is unacceptable. Set boundaries and communicate the importance of loyalty in the relationship.
One should first stay calm. If it makes you uncomfortable, gently let her know that this topic is not appropriate for you to discuss at the moment.
Politely change the subject. Maybe start talking about the beautiful scenery during the vacation instead of the sexual aspect. Say something like 'You know, that beach we went to was so beautiful, let's talk about that.' This way, you can avoid the discomfort of the inappropriate topic without making her feel bad.
First, stay calm. If you're comfortable with it, you can engage in a conversation about it. If not, gently let her know that it makes you uncomfortable.
One could calmly tell her that such stories are not acceptable in their relationship and ask her to refrain from sharing such content in the future.
