Exploring Boundaries in an Open Relationship

I've been in an open relationship with my partner for over a year now. It’s given me the freedom to explore different aspects of myself and my desires, but it's also brought up some intense emotions that I’m still working through. Recently, I connected with someone who shares my interest in a more submissive roleplay dynamic. We met at a BDSM event where I found myself completely captivated by his confidence and authority. The physical intimacy was raw and powerful, he took control of the encounter from start to finish, guiding me through every moment with firm hands and authoritative words that sent shivers down my spine. His fingers delved deep inside me as I surrendered fully to him, feeling utterly at his mercy but safe within the clear boundaries we’d set beforehand. His cock slipped in effortlessly, filling me completely and drawing out moans of pleasure from both of us. As he pounded into me with precise thrusts that hit all my spots, my senses heightened; every touch felt electric, every sound amplified to a fever pitch. I've always been curious about power dynamics but this was the first time I embraced being on the receiving end so fully. It left me feeling exhilarated and questioning myself, am I drawn to submission beyond just roleplay? What does it say about my relationship with my primary partner, who’s never expressed interest in such dynamics? What do you think? Have you explored similar kinks or power dynamics in your relationships?
