Out of a Relationship and Seeking Advice

I recently ended things with my long-term partner after six years. We were both mature adults going through life's changes together but ultimately decided it wasn't working out anymore. It was an amicable breakup, but I feel conflicted because we explored many intimate acts during our time together, ones that are less common and would be hard to find again in a new relationship. For instance, there was this one night where he introduced me to sensory deprivation bondage with blindfolds and earmuffs, something surprisingly thrilling and freeing at the same time. Now, I'm wondering if it's normal to feel such nostalgia for these experiences as I move on. Is anyone else out there in a similar situation?
