Emotional Vulnerability in Play

I am a doctor, in my mid-thirties, and recently started exploring the Daddy/kink scene. I find myself deeply moved by this dynamic; it's more than just roleplay to me, but part of who I've become. Recently, during a session with my partner, a young woman also well into her adulthood, we experienced something quite profound yet challenging. She needed discipline, and while performing my duty as her Daddy, I felt an overwhelming surge of emotion mixed with a sense of intimacy that left us both shaken. How do others navigate such intense emotional connections within this context? Is it common for feelings to run so deep during play?
