Yes, it is clearly an inappropriate interest. Such a topic is private and should not be a subject of interest among people in this relationship. It violates the normal boundaries of friendship and marriage.
You might also need to have an open conversation with your wife. Explain the situation to her without causing unnecessary misunderstandings. Maybe she can help handle this delicate situation. For instance, she could talk to her friend and make it clear that such behavior is not proper in the context of your relationship.
This situation might suggest that your girlfriend is very attracted to you physically. But it's important to look beyond just the physical aspect. If the relationship is only about this, it might not be sustainable. You need to build other aspects like mutual respect, understanding, and shared interests. Maybe start having deeper conversations to strengthen the emotional bond.
Sharing such a story is highly inappropriate as it involves private and inappropriate details about a family member. Family members' privacy should be respected, and this kind of content is not suitable for public discussion.
You can respond in a positive and respectful way. For example, you can show that you appreciate her attraction but also remind her that there are other aspects of you and the relationship that are important.
You could look for adventure stories with heroic characters. They often have elements of grandeur and excitement that might appeal to her love for 'big' things in a more appropriate way.
Share stories that promote family values such as unity, support, and love. For instance, a story about how the family came together during a difficult time. Make sure the story is something that can be told in all family settings without causing embarrassment.
Well, it's important to approach this delicately. Start by expressing your feelings without sounding accusatory. You might also suggest exploring other forms of literature or stories together that are more in line with both of your comfort levels and relationship values. This way, you can build a stronger emotional connection based on mutual understanding and respect rather than being fixated on something that makes you uneasy.
