No, it's not ethical. Everyone has their own sexual orientation, and forcing or seducing someone who is straight to engage in a lesbian relationship violates the other person's will and boundaries.
In most cases, it's not right. A straight girl may be very uncomfortable with such advances as she is attracted to the opposite sex. It's important to respect the fact that people are different in their sexual preferences and not try to force or manipulate someone into a relationship that is not in line with their natural inclination. For example, if a straight girl is in a situation where she is constantly being pressured by a lesbian's seductive behavior, it can cause her a great deal of distress and confusion.
It is generally not ethical. Everyone has their own sexual orientation, and trying to force or seduce someone into a relationship that goes against their natural orientation can be a form of manipulation. A straight girl may be confused or uncomfortable with such advances.
Sure, but these stories can be quite complex. Some may seem like a simple case of attraction, but often there are deeper psychological and social aspects involved. In a community center, there was a situation where a lesbian woman was part of a group that included a straight woman. The lesbian was charmed by the straight woman's personality. She tried to get closer by inviting her to various events. But the straight woman, being straight, was initially confused and then had to gently decline further advances to maintain her own sexual orientation boundaries.
I'm not aware of many such stories in mainstream literature. However, in some indie or niche works, there might be themes that touch on complex relationships. But promoting or focusing on seduction in an improper way is not a positive or common literary theme.
No. Such a story involves inappropriate and unethical behavior, especially when it comes to an adult seducing a high school girl who is a minor. It can promote negative and harmful values, and it is not suitable for media to spread this kind of content.
In a straight girl lesbian story, a common theme is the power of friendship. It often starts as a strong friendship between the straight girl and the lesbian character. Also, confusion is a big theme. The straight girl is usually confused about her new - found feelings and how they fit into her previous understanding of herself and relationships. There is also the theme of breaking boundaries, as she steps out of what society might expect of her as a 'straight' person.
