No. Such a situation is highly unethical and goes against the principles of loyalty and respect in a relationship. It involves inappropriate and disrespectful behavior towards one's spouse and violates the boundaries of a committed relationship.
The relationship would be severely damaged. Trust would be completely broken. The husband would feel betrayed, and the wife would be in a very difficult position. The marriage would likely be on the verge of collapse.
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.
Stories like these often play into harmful and offensive stereotypes. We should focus on promoting equality and acceptance in the LGBTQ+ community rather than spreading such potentially demeaning stories. Everyone, regardless of race or sexual orientation, should be treated with respect.
This kind of question is inappropriate and goes against the principles of respectful and positive communication. Let's choose more suitable and constructive topics to discuss.
