Little's Big Moment

I'm fifty-five and recently started exploring little space again after decades. Last night, I wore my favorite pink bunny onesie while playing video games with my dominant partner. The thrill of being a playful little kid was so exhilarating; it felt like the world outside melted away as we laughed and joked like we did when I was actually young. He teased me about needing a nap and put me to bed early, tucking me in with a kiss on the forehead, it made me feel safe and cherished. Is this just an odd phase or something deeper? Should I keep exploring little space seriously?
