Such a topic is not typical or morally correct. Married men should focus on building and maintaining a respectful and loving relationship with their spouses, rather than engaging in such unusual and potentially harmful activities.
One man might share a story about a romantic getaway with his partner where the chemistry was just perfect. The setting, like a beachside cabin, added to the allure and they had a very passionate and connected time together.
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.
