I can see where you coming from. You described them based on their characteristics and past situations. Bottom came from more of negative background, where he was in a more constant state of fight-or-flight. The top came from a more leadership/caretaker background. So I can see why you thought the problem may be due to each individuals personal situations and how it can impact their relationship.
So basically, there’s an imbalance in their love for one another. Top keeps pushing to not bite his nape and bottom is disappointed that he won’t. Which causes him to doubt his love for him. These factors ultimately causes the top to no longer smell the bottom’s scent.
So to counteract these issues, they simply need to communicate. Sighhhhhh….. why is communication always the issue (╯°Д °)╯╧╧ (unless bottom is pregnant)
