Learning the Ropes as a Submissive

I've always felt like there was something missing in my life. A part of me wanted to explore something new and different, something that would bring out parts of myself I didn't even know existed. So when I met someone who introduced me to DDLG dynamics, it was both thrilling and terrifying at the same time. It's been a few months now, and we've started to really dive into this lifestyle together. There are times when I feel like the most submissive person in the world - doing whatever he asks without question, even if it challenges my comfort zone or self-image. But there are also moments where I'm so happy and fulfilled, feeling cared for and cherished in a way I never thought possible. Is this normal? Am I playing a role that's not really me? Or am I just learning to embrace a new side of myself? Any advice from anyone who's been through something similar would be greatly appreciated.
