This statement is very unclear and rather strange. 'Cum' has multiple meanings in English, but if we assume it's the vulgar meaning, it's inappropriate content. If 'cum' is used in other non - vulgar senses like 'come' in a non - standard way, it still makes little sense without more context. Maybe it's a very poorly worded or misspoken statement.
You can choose a calm moment, like when you're having a quiet dinner or a walk together. Start by saying something like 'Love, I've been thinking about the stories you share sometimes. The ones about showing too much really bother me. I feel it's not appropriate for our relationship.' Then, listen to her response and have an open - ended conversation about it.
Sharing such stories is completely inappropriate and violates privacy and social norms. This is a very private and inappropriate topic that should not be publicly discussed.
This kind of interest is not in line with the norms of a healthy relationship. A good marriage relationship should be built on positive emotions, common goals and positive communication. You can try to introduce some positive literary works or movies to your wife to guide her interests to a more positive direction.
Exposing one's body in an inappropriate way in public is not acceptable behavior. However, if it was an accidental exposure, it might be a different situation. But in general, such behavior goes against social norms of modesty.
First, have an open and honest conversation with her about how such content is inappropriate and not in line with positive values. Then, suggest some positive and interesting alternatives like reading inspiring books or watching heartwarming movies together.
You can start from your own memories of when you first met and the early days of your relationship. Recall the moments of attraction, like the first time you held hands or the first kiss. Build a story around those emotions and experiences.
