Confused About My New Kink

I'm a nurse in my 30s and have always been very professional at work. Lately though, I've started exploring kinks outside of it that are making me feel conflicted. It all started when I met this person online who suggested we try something called Daddy Dom/Little girl roleplay. I didn't know much about it but felt drawn to the idea of being cared for and protected in a way my professional world doesn't offer. At first, it was just talking and sending playful messages back and forth - things like calling me 'sweetie' or telling me what he expects from me as his little girl. I enjoyed feeling spoiled and wanted, even if it's not something I'd ever openly admit to others. The physical aspect started last week when we decided to video chat more frequently. During these chats, my 'daddy' would sometimes use a hand-cuff set of his, holding one wrist while he guided me through activities - things like him feeding me candy or commanding me on how to dress myself for the next day. It was exciting and made me feel vulnerable in ways I've never felt before. We even talked about using toys that are meant for bondage but with very gentle play. Today, we took it further than ever before though - he ordered me to strip down completely and then began touching me in ways that were so intimate yet so different from what I usually experience. It was thrilling and also a bit scary how much control he had over the situation. I'm not sure if this is normal for someone just starting out or if I need to back away. Am I being manipulated, or am I simply exploring new depths of myself that are safe as long as both sides agree? I love my job but it doesn't offer me these kinds of connections or the chance to feel taken care of and protected from adult responsibilities. Is what we're doing normal? Should I be concerned about where this is heading?
