Definitely not. These types of stories are not in line with the values of respect and propriety. Coed showers are meant for normal bathing and personal hygiene purposes, and introducing sexual elements into this context is inappropriate. It can also make people feel uncomfortable and offended.

Public discussions should be centered around positive, educational and respectful topics. Coed sex stories are not in line with these criteria. They can make people uncomfortable and violate social norms.
No. Most fanfiction communities have strict rules against sexually explicit content. These types of stories violate the community's standards of decency and respect.

Definitely not. Public discussion of these types of stories is unethical. These are very personal and private matters that should be kept within the appropriate boundaries. It can also make others uncomfortable and is not in line with the values of a respectful and inclusive community.
