Proud of My Little Space Play

I'm a personal trainer who's also the proud Mommy to my submissive partner. We've been exploring little space play for about six months now, and I must say it has brought us closer together in ways that surprise even me. Our sessions are always consensual and end with him feeling loved and cared for, but I wonder if others find this dynamic unusual or unhealthy? Is it normal to feel such a strong bond while playing the role of Mommy? Any advice or insights would be appreciated.
