No. These types of stories often objectify and can be demeaning to people. Subliminal messages in such stories usually promote non - consensual or unethical relationship models.
There are multiple ethical concerns. Firstly, it blurs the line between human - like entities (robots in this case) and sexual objects. Secondly, it can have a negative impact on how people perceive relationships.

In most cases, they are not appropriate. Mainstream literature typically aims to promote positive values, and these kinds of stories with their often explicit and unethical overtones go against that. For example, they can objectify and disrespect relationships, which is not what we want to encourage in a general reading public.
Most mainstream literature does not focus on such themes as they are considered inappropriate and violate ethical and moral norms. However, in some underground or niche forms of writing that are not part of the mainstream literary world, there might be something, but it is not something that should be widely promoted or discussed.
