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.
Always think before you speak. If a topic seems to be veering into vulgar or inappropriate territory, steer clear of it. For example, focus on hobbies, work, or current events instead.
This kind of description is unacceptable. Society has moral boundaries, and we should focus on positive, healthy and ethical topics instead of such disturbing and inappropriate ones.
