My First Time Being a Little

I've always had an interest in DDLG dynamics, but I never thought I'd actually experience it. Last weekend, I met someone online who proposed we try out a little space role-play. Despite my nervousness, I agreed, and we set up a time to meet. When he arrived, he took charge right away, reminding me of rules and boundaries in a way that was both strict and caring. As the session progressed, I found myself completely immersed, feeling like an eager child learning from a patient mentor. It felt strangely liberating but also a bit uncomfortable. Am I overthinking it? Is this something others find normal or healthy? What advice do you have for someone starting out in this dynamic?
