The Software Engineer Daddy's Little Secret

I've been involved with DDLG (Daddy/Domestic Discipline/Little) for the past year and a half, ever since I turned 35. It started as an online interaction on a kink forum where I met my little girl, who's now in her early twenties. She wanted to explore this dynamic because of its emotional support benefits, but it quickly evolved into something more physical and intimate. Our arrangement is consensual and involves regular check-ins via video calls where she addresses me as 'Daddy' and behaves in a way that aligns with the little persona she's developed. Sometimes, I'm her strict enforcer and disciplinarian; other times, we indulge in sexual activities that cater to both of our fantasies within this dynamic. Last night was particularly intense. She'd been acting out slightly more than usual due to some stress from work. After a few days of ignoring my texts, she finally responded with an apology. We set up a call and I gave her some stern discipline, a spanking that left marks on her bottom, paired with verbal reassurance. The aftermath was surprisingly tender; we ended up making love after our session. I'm proud of how this relationship has evolved, but sometimes I wonder if there's an unhealthy element to it that I'm missing. We're both adults and the boundaries are clear, yet there's always a lingering question in my mind: Am I the asshole here for enjoying this level of control and dominance? Or is everything perfectly normal as long as we're both consenting and happy? Your thoughts would mean the world to me.
