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 could recommend classic coming - of - age stories like 'The Catcher in the Rye'. It's a great exploration of teenage angst and growing up. Another option is 'Anne of Green Gables', which is full of charm, friendship, and the adventures of a young girl. Also, 'To Kill a Mockingbird' is an excellent choice as it deals with important themes like justice and prejudice in a very engaging way.
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 is inappropriate content. We should not spread or discuss stories that are inappropriate or violate others' privacy regarding a teenager in such a vulgar way.
Well, here's one. There was a rooster on a small farm. This rooster was really proud. Every morning, it would wake up the whole farm with its loud crowing. It was so protective of the hens in the coop. Once, a fox came near, and the rooster bravely stood in front of the hens and flapped its wings furiously, scaring the fox away.
