Just Figuring It Out...

I'm really new to this and I feel so weird typing all of this out. Can't believe how far I've gone with my partner just in the last few months. She's 35, but sometimes she acts like a playful little girl, asking me questions about school or playing hide-and-seek around the house. It started when we were watching some movie where the character got spanked and laughed it off like it was fun. Next thing I knew, I found myself spanking her back, lightly at first, then harder as she giggled and kept asking for more. The physical stuff is so intense but also feels so freeing. She's been letting me tie her up sometimes too, blindfolded with just a little gag in her mouth because she enjoys feeling helpless like that. It makes me feel dominant, which is something I never thought would be my thing. But now it's become such an important part of our intimacy and connection. Sometimes I worry people will find out and judge us, but when we're together it feels so right. We don't talk about it much outside the bedroom, but inside, all bets are off. She calls me daddy sometimes and that sends chills down my spine every time. It's a bit embarrassing to admit this out loud even here, but I'm starting to think maybe there's nothing wrong with giving into these desires as long as both of us want it and enjoy it.
