Our Kinky Journey

I'm in my early thirties, and we've been doing some deep DDLG role-playing recently with my partner who's always taken on a mommy role with me. It started out as light-hearted play but has grown into something deeper... I mean, there are moments where I feel so safe and cared for, like no worries in the world matter... Then other times it can be intense, strict discipline that makes me squirm and feel small... And oh boy, when we get intimate afterwards, wow. There's this raw energy between us that feels both terrifying and exhilarating all at once. It's strange to think that this dynamic has become such an integral part of our relationship now... Does it make sense for long-term couples to explore these kinds of dynamics? I feel a bit lost sometimes but also deeply connected.
