A Little Space Experiment

I've always been interested in the dynamics of power and control within relationships. After reading about DDLG and little space scenarios online, I decided to explore this concept as a mental exercise rather than something I'd enact physically. Recently, I initiated a conversation with my long-term partner where we agreed on me taking up an adult little roleplay for a period, primarily focused on emotional dependence and some playful age-play dynamics. He acts as my 'parent', offering guidance and support while also engaging in light disciplinary scenarios when needed to keep boundaries clear. I've found the experience surprisingly cathartic; it has allowed us both to express feelings and needs we might not normally discuss openly. However, I'm starting to question whether this setup is normal or beneficial for a mature relationship. Are there any specific psychological benefits that come from such roleplay dynamics in committed relationships? Or am I overthinking everything?
