There are a few. However, they are usually part of very old or extremely complex literary works. These stories are not common in mainstream literature as such themes are considered unethical. In some classic European literature, there might be some allusions to improper family relationships which could be related to this, but they are more about exploring moral and psychological boundaries.
Well, it depends. In some cases, if the seducing sex stories are part of a larger exploration of human nature, such as in certain works of psychological or relationship - based literature, they could be considered appropriate. But if they are just for the sake of titillation, then no. Modern literature should strive to promote healthy values and meaningful content, and most of the time, such stories don't really contribute to that.
No, it is completely unethical. In a marriage, there is a commitment between two people. Seducing a married woman violates the trust within that marriage and can cause great harm to many people, including the woman's spouse, children if there are any, and the woman herself.
No. Seducing someone's wife is unethical behavior that violates the principles of marriage and respect for others. It can cause great harm to a marriage and the people involved.
No. The concept of a mother seducing her son is highly unethical and inappropriate, and there should not be such stories in proper literature. Literature generally promotes positive values and healthy relationships.
In proper literature and mythology, such themes are extremely rare and not in the form of what is wrongly implied. Most stories in literature and mythology uphold moral and ethical values. For example, in Greek mythology, family relationships are complex but not in this inappropriate way. There are more stories about heroic deeds, love between proper couples, and the struggle between good and evil.
In modern society, such stories are generally met with strong disapproval. We have a much stronger sense of ethical and moral boundaries today. Any form of incestuous or inappropriate family relationship themes are considered unacceptable and go against our values of healthy family and social relationships.
This is not at all appropriate. It violates basic human values and the healthy development of family relationships. We should focus on positive and healthy family interactions instead.
There is also the potential for objectification. When girls are seen as 'seducers' in a story, it might reduce them to sexual objects rather than complex individuals with emotions, desires, and rights. This can contribute to a culture that doesn't respect women fully.
