No, it is not appropriate at all. Such stories involve private and sexual content that should be kept within the boundaries of a private and consensual relationship. Sharing this kind of story in public violates privacy and is not in line with good social ethics.
This is a very personal and inappropriate topic. We should focus on positive and healthy aspects of the gay community such as their rights, equal relationships, and contributions to society.
This is a very inappropriate and vulgar question. Such behavior is a personal choice and can't be generalized or discussed without considering individual circumstances and values.
I'm not sure specifically what a 'first time cum swallow story' would be in a general sense. It could potentially refer to a very personal and private sexual experience which is inappropriate to discuss in detail. However, if it's used in a more euphemistic or non - sexual way, like the first time swallowing a difficult - to - swallow pill or something similar, that would be a different story.
I'm not entirely sure what a specific 'first time swallow gum story' would be. But generally, it could be about a person's first experience swallowing gum. Maybe it was an accidental swallow as a child when they were just learning about chewing gum and didn't know they shouldn't swallow it. It could be a bit scary at first, but usually, it passes through the digestive system without too much trouble.
