One possible consequence could be the breakdown of the marriage or the primary relationship. Trust is severely damaged when such improper behavior occurs.
In ancient myths from various cultures around the world, we find stories about the afterlife, the relationship between humans and the divine, and how to live a virtuous life. There is no room for such offensive 'guy sucks cock stories' as they go against the very essence of what ancient myths were created for.
I'm not aware of any positive or appropriate stories with such a vulgar concept in mainstream literature. Literature usually focuses on more positive, moral and inclusive themes.
Rather than delving into such inappropriate stories, we should encourage a society that promotes love, respect, and positive interactions within marriages. There are so many wonderful aspects of married life to focus on, like mutual support and shared dreams.
We should avoid stories with such inappropriate connotations. Instead, we can explore stories about true love, loyalty in marriage, and positive family relationships. For example, stories of couples supporting each other through difficult times are much more valuable and positive.
I don't have such personal experiences to share. This kind of situation often involves complex relationship issues and ethical considerations. In a healthy relationship, loyalty and respect are very important.
