Ancient mythologies have their own set of themes and motifs. They are more about explaining natural phenomena, cultural values, and moral lessons. Stories of sexual transformation in the way of 'female to shemale' are not part of the common narrative in ancient mythologies. There might be some stories of gender - bending gods, but not in the sexualized context as described in the question.
Shemale sex stories involve complex ethical considerations. On one hand, they can often be part of the adult entertainment industry which has its own set of moral debates. In many cases, these stories might objectify individuals. However, if they are told in a context of promoting understanding and respect for the transgender community, it could be different. But generally, in the form of just sexual stories, they tend to cross ethical boundaries as they can reduce people to sexual objects.
In general, it's difficult to find positive and non - offensive 'female to shemale sex stories' as such topics often involve inappropriate and objectifying content. Instead, we can look at stories that deal with transgender experiences in a respectful way, like memoirs of transgender individuals where they talk about their journey of self - discovery and acceptance, which has nothing to do with sexual objectification.
Most of the well - known literature tends to center around more general human relationships like love, friendship, and family. Themes like'shemale on male sex stories' are not common in the literary world because they are considered to be too niche and not suitable for a wide audience.
Sharing such stories is highly unethical. These types of stories often involve non - consensual and inappropriate content. Prison is a place where people are supposed to be rehabilitating, and spreading such salacious and improper tales violates the privacy and dignity of inmates and goes against basic moral and ethical standards.
Sharing such stories is inappropriate as they often involve adult and inappropriate content. We should focus on positive, family - friendly and respectful topics.
