No. In most moral and ethical frameworks, having sex with a married woman is not considered ethical. Marriage is a commitment between two people, and having an extramarital sexual relationship violates that commitment and can cause a great deal of harm to many parties, including the woman's spouse, children if there are any, and the woman herself.
One consequence could be the breakdown of the marriage. The husband may find out and become angry, leading to separation or divorce. Another consequence is the social stigma. The woman and the person she had sex with might be shunned by society in the context of the story.
However, in more conservative parts of society, it can be met with shock, confusion and even condemnation. Traditional views on sexual orientation often struggle to understand how a self - identified straight woman could have a sexual relationship with a woman, and this can lead to the woman facing social stigma, discrimination or at least raised eyebrows from family, friends and the community at large.
Sharing such sexual stories violates the privacy and dignity of transgender women. Instead, we can talk about how to build healthy relationships with transgender people based on respect, communication, and mutual understanding, without delving into sexual aspects.
Yes, it is highly unethical. Teachers are in a position of power and authority over students. Having a sexual relationship violates professional boundaries and can lead to exploitation of the student, whether it's emotional, physical, or both. It also goes against the code of conduct in educational institutions.
It's not appropriate. Fanfiction usually focuses on more reasonable and acceptable fictional scenarios based on existing fictional universes. Combining a woman and dinosaurs in such a sexual way is not only abnormal but also not something that would be widely embraced in the fanfiction community.
Well, adventure stories are great alternatives. For example, tales of hiking in the mountains, facing challenges like bad weather or difficult terrains and still reaching the summit. It's full of excitement and the joy of conquering nature.
