Been Sliding Into The BDSM World Slowly...

Hey there, I'm a personal trainer in my mid-thirties who's been happily married to my wife for five years. We both lead pretty healthy and normal lives but recently we've started exploring the world of kink... it's honestly kind of blowing my mind right now. We've always had a decent sex life, but nothing extraordinary. I'd call us vanilla for sure. A few months ago she got me a collar as an anniversary present, saying she wanted to explore being our own little power dynamic between just the two of us at home. It was strange and exciting and it's been growing ever since. She calls me her boy now, and we're trying this up-down roleplay where I submit and listen while she gives direction... But honestly, it's starting to feel like more than a game. The way she talks about how much she wants control is kind of intoxicating - but at the same time, scary as hell. I'm not sure if I'm ready for that level of vulnerability or giving up my independence. I told her all this, and we agreed it's okay to go slow, take our time with whatever turns out to be right for us... But there are these moments where she'll look at me with this intense gaze and I just lose myself completely. It's overwhelming but exhilarating too. Sorry if this is confusing - it's all so new and I'm still trying to figure everything out. Posting here helps me process my thoughts a bit, even if no one responds. We're adults making choices together that feel right in the moment... isn't that what matters?...
