The Dark Side of My Little Space

I never thought I'd be here, confessing something so intimate to strangers on the internet. Ever since turning 18+, my life has felt more open and less restricted in many ways, but this part of me feels like a secret locked away. A few weeks ago, during a particularly tough shift at work, I found myself daydreaming about returning home to an older authority figure who would take care of me as if I were his child. It's not that I'm attracted to parents or anything unhealthy, I assure you that isn't the case, but there’s something comforting and thrilling about being treated like a little one in these fantasies, even though I’m well into adulthood now. Last night, after weeks of building up the courage to act on this strange desire, my partner surprised me with a gift: a pair of children's pajamas. As much as it made me feel small and vulnerable, there was an exhilarating rush when he put them on me himself, telling me I needed rest and care before going out again today. He didn’t use any real authority or spank me or anything, just dressed me up like a kid who needs help. And yet...oh my god, it felt incredible. I've never been this way before. Is it normal to get such intense pleasure from feeling so small and helpless? What does this mean about me?
