Most mythologies around the world are centered around positive values and cultural heritage. Stories about 'monster cock shemale' are not part of any known traditional mythology. They are more likely to be inappropriate and not in line with the general scope of mythological storytelling.
I don't have a personal experience in this regard. However, any sexual encounter should be based on mutual respect, understanding, and safety within the boundaries of legality and ethics.
There are no such stories that would be appropriate for all ages. The concepts involved are not family - friendly or acceptable in general public - oriented storytelling.
Stories about animals in the wild can be really interesting. For instance, the story of a mother lion protecting her cubs. It shows the power of maternal love.
Rather than dealing with such potentially offensive content, we can turn to positive stories like tales of friendship and kindness. For example, the story of how a group of friends supported each other through tough times.
They can be considered a bit of both. In many cultures, such topics are considered taboo due to their sexual nature. However, from a personal experience perspective, some might see it as part of their sexual exploration journey. But it's important to note that these are very private and not something to be shared casually in all social settings.
Sharing such a story is highly inappropriate as it involves private and inappropriate details about a family member. Family members' privacy should be respected, and this kind of content is not suitable for public discussion.
One story could be about a power top shemale in the fashion industry. She overcame many prejudices and became a top model. With her unique charm and strong will, she strutted down the runways, inspiring others in the transgender community. She showed that being a power top in this context meant taking charge of her own image and career, and not letting others' opinions hold her back.
