How should a husband and wife react when hearing friends' sex stories?

Well, it can be a bit awkward. You could just smile and change the topic. You don't really need to get into details or pass judgment. Maybe say something like 'That's an interesting story, but let's talk about the cool places you visited instead.'

He should first listen calmly. If he's comfortable, he can engage in the conversation and share his thoughts. But if he feels uncomfortable, he should gently let her know.

She could start by having an open and honest conversation with him. Let him know how she feels about it.

I think it's best to be respectful. If it's a private story that was shared with you, keep it to yourself. Don't spread it around like gossip.

He should first listen calmly. If he feels uncomfortable, he can gently tell his wife that this topic makes him uneasy. For example, he could say 'Honey, I don't think I'm comfortable with this kind of story.'

One should firmly but politely let the friend know that this is an inappropriate topic. For example, you can say 'I don't think this is something we should be talking about. It's very private.'

She could try to get to know the man better herself. By inviting him over for dinner or joining them in some activities. This way, she can ease her concerns and also understand the nature of their relationship better. If she finds out he's just a harmless friend, she'll feel more at ease.

He should listen attentively. Just give her his full attention and show that he's interested in what she has to say. For instance, make eye contact and nod occasionally.

If you're the husband, the first step is to communicate calmly. Don't jump to conclusions right away. Just tell her how you feel when you hear such stories. Maybe she didn't realize how her dancing made others perceive her.

He should try to have an open conversation with his wife. Let her know how he feels about her only sharing her side and how it might be affecting their relationship and his reputation among her friends.
