No, it's not appropriate. Sexual experiences are private matters between two people. Sharing such stories without the wife's explicit consent is a violation of her privacy.
There are many positive relationship stories. For example, a wife might bring home a special gift she found during her day out, like a book that her hubby has been wanting to read. It shows her thoughtfulness and care for him.
A wife could bring home a beautiful flower from the garden and give it to her hubby. It's a simple yet sweet gesture that can brighten his day and show her love.
Hubby could start a conversation about different types of stories in general, and then gradually steer it towards flirt stories. He could share some of his own interesting or funny stories first to make her feel more comfortable and then ask if she has any similar ones.
Definitely not appropriate. Privacy is a fundamental aspect of any relationship. The hubby may have shared things with his wife in the confidence of their relationship. By sharing those stories, the wife is breaking that trust. It could also make the hubby feel exposed and vulnerable, which is not healthy for the relationship. This kind of behavior might stem from a lack of respect for boundaries or a need for attention, but it's wrong either way.
Sure. In one story, the hubby is driving to a community event. The wife and the stranger, who turns out to be a volunteer for the same event, start discussing their roles. They bond over their shared passion for helping the community. By the time they arrive, they are excited to work together, and the hubby is proud of his wife for making a new connection.
One story could be that the wife is a fashion designer and she wants her hubby to understand the different styles and feelings of clothing. So she encourages him to crossdress for a day. He initially resists but then finds it quite an eye - opening experience as he discovers how different fabrics feel against his skin and how different styles can change one's appearance.
It's not entirely clear without more context. 'P' could potentially stand for many things like 'pet' or 'personal'. Maybe they are sharing some other personal stories about their experiences together as a couple.
