Well, in the world of literature, you don't often find such a blatant theme. There are so many other aspects of human relationships to explore. For example, love, trust, and communication between a husband and a wife are far more important and commonly written about. This kind of theme is more likely to be found in very specific, perhaps less - respected types of writing.
Using such expressions is not acceptable in civilized conversation. We can talk about things like building good relationships, mutual respect in marriage, etc.
Well, it depends on the relationship dynamics. In some relationships, open communication is so good that there's no need for begging. But in others, especially when there are differences in priorities or resources. For instance, a wife might beg for a home renovation if she's been dreaming of a new kitchen for years, while her husband is more focused on saving for retirement. So in some situations, these types of stories are common.
Stories where a wife 'begs for it' can vary greatly. One could be a story where the wife begs for a chance to pursue her long - lost dream of painting. She pleads with her husband to let her take time off from household chores and attend art classes. Another might be about a wife begging for a family vacation to a place she has always wanted to visit, like a beach town. She presents all the reasons why it would be good for the family, from relaxation to new experiences.
