A Secret Sado-Masochistic Twist in Our Relationship

So, I've been keeping a big secret from my partner for months now. We have this wonderful relationship that's been going strong since we started dating three years ago. Everything is great except... well, there's this thing I'm really into and it’s kind of scary to think about sharing it with him because it feels so different than what we usually do together. It all started when I went to a kinky club one night with some friends from work. I was super nervous but also excited. As soon as I stepped inside, there were all these people in leather and chains, talking openly about their fantasies. It was shocking and exhilarating at the same time. And then something happened that changed everything for me. I saw this one guy who had this intense presence about him; his eyes just locked onto mine from across the room. We made eye contact and he walked right up to me, asking if I wanted to try out a little role play with him. I was hesitant but also curious, so I agreed. Let me tell you, it opened a whole new world of feelings for me. He tied me up and everything felt so intense and alive. It wasn't just about the physical sensations, it was the trust and power exchange that really got to me. Since then, whenever I fantasize, I’m thinking about those moments back at the club. Now here’s where it gets complicated: Lately, when we're alone together, all these thoughts pop into my head about wanting to explore something similar with him. The thought of tying him up and really taking charge feels so good, but I'm worried he won't understand or want to try it out too. I don’t know what’s going to happen next, but one thing is certain, I can’t keep this secret forever. It's eating at me knowing that there might be a whole side of our relationship we haven’t even begun to explore yet.
