It is completely unethical. Watching any form of nude or private story without the person's explicit consent, even if it's your wife, violates privacy and basic moral principles.
If a wife visits a first nude beach, there are many possible scenarios. She may be shocked by the lack of clothing at first. However, as she acclimates, she might notice the beauty of people being comfortable in their own skin. She could be inspired to be more confident about her own body. There might also be some cultural differences she has to navigate, for example, different attitudes towards nudity in different regions. And she may need to figure out how to relax and enjoy the beach environment while still respecting the boundaries and privacy of others.
No. Watching someone's nude story without their explicit consent is a serious violation of privacy and ethics, even if it's your wife. Everyone has the right to control who sees their nude or private images.
Definitely not. In a healthy relationship, mutual respect for privacy is crucial. If your wife has something she considers private, such as a nude story, you should respect that. Looking at it without her okay could make her feel violated and betrayed, which can have serious negative impacts on your relationship, like causing arguments, and making her feel less secure in the relationship.
This is a rather complex and subjective matter. In a private, consensual relationship context, some couples might explore such ideas within the boundaries of mutual respect and privacy. However, if it makes you uncomfortable or goes against your values, it's important to communicate openly with your wife about your feelings.
I'm not sure what exactly your wife's 'goes on a date' story is. If she went on a date with you, it could be a lovely story of getting to know each other better, sharing a meal and having great conversations.
