This is a highly inappropriate and offensive question. There is no valid or acceptable way for such a disturbing and immoral situation to be presented in stories. We should encourage positive and beneficial content in literature.
Definitely not. Such a topic involves improper and unethical content that violates social and moral norms. There are so many other good topics to talk about like cultural events, scientific discoveries, etc.
One way is to set some basic rules for communication, whether it's in family, social or work settings. Make it clear that vulgar topics are not allowed. Also, we can educate ourselves and others about the importance of positive and respectful communication.
There is no evidence to suggest that such activities occur in a gym environment. Gyms have rules and ethics in place to maintain a proper and respectful atmosphere for all members. This kind of description violates the basic norms of a public fitness place.
Most literature aims to promote positive social values, and topics like this are not part of the acceptable content in literary works. We should look for stories that are about love, friendship, and moral growth in literature.
