It's natural for the dynamics of a relationship to evolve over time and for the intensity of certain aspects, like sexual conversations, to ebb and flow. It's possible that your partner may have wanted to move away from solely focusing on physical intimacy to cultivate a more balanced and meaningful connection with you. Communication is key in situations like these. I would recommend having an open and honest conversation with your partner about your feelings and desires. Express your thoughts in a respectful manner and listen to their perspective as well. This will help both of you understand each other better and work towards maintaining a healthy and fulfilling relationship.
