The Big Secret I've Kept from My Partner for Years

I've been exploring the world of DDLG and age-play since I hit my mid-20s. As a switch, there's something incredibly freeing about stepping into both roles, sometimes feeling like a little one again, other times embracing the responsibility of being the caregiver. My partner knows me in every other aspect, but there's this secret life I lead that I've kept hidden for years. It started with an online community where everything is consensual and safe spaces are maintained for exploration and growth. I found myself deeply drawn to the dynamic between a protective father figure and his little one, even though my own childhood wasn't anything like it. In real life, I'm quite independent, but in these role-plays, I revel in being taken care of, from bedtime stories and morning hugs to playful scoldings that feel more loving than disciplinary. My caregiver persona is the polar opposite: strict yet nurturing, always there to support my little side but also ready to set boundaries. It's not about abuse or control; it’s a consensual space for mutual growth where we both find peace and joy in this dynamic. The dilemma comes when I realize how much of myself I’ve poured into these characters that aren't really me, they're an escape, yes, but also a part of who I am now. As someone who's approaching their 30s, do I share this side with my partner and risk everything for the chance at deeper intimacy? Or do I keep it hidden and live in fear of losing something I adore? So here’s my question to you all: Is keeping a major part of yourself from your partner okay if it's not hurting anyone and brings so much joy? Am I being selfish, or is there a way to balance these two sides of me?
