Sharing sex position stories is inappropriate and goes against ethical and moral standards. We can focus on positive relationship topics like communication in a relationship instead. Good communication helps partners understand each other's needs and desires better, which is crucial for a healthy relationship.
Sharing stories about anal sex positions is not appropriate in most public or general social settings. Such topics are considered private and sexual in nature, and should be kept within the boundaries of consensual adult relationships and appropriate educational or medical discussions. In a public or general conversation context, it goes against social norms and can make people uncomfortable.
We could also discuss fitness and healthy living as a couple. Exercising together, cooking healthy meals, and motivating each other to lead a healthy lifestyle can be really beneficial for both the individuals and the relationship as a whole.
Well, I don't think it's appropriate to share such stories directly as they are very private and personal matters. It's better to keep these topics within the boundaries of a private and consensual relationship.
Yes, there was an ancient novel that matched this plot, and that was "The Power of the World: The Princess Consort is Extremely Beautiful." In her previous life, the female protagonist, Mu Zhixi, let down the man who doted on her like her life and helped the scumbag ascend to the throne. In the end, she was betrayed and cruelly killed by the scumbag and his step-sister. After her rebirth, she slapped the scum in the face and returned home with her husband. I hope you like my recommendation, muah ~
