Lost in the Moment

So I guess this is my first time posting here. I'm feeling kinda raw and embarrassed but also really honest about it now that a week has passed. Here's what happened, all of it, just as it went down... I met Alex on one of those dating apps. They seemed sweet, open-minded, and very casual from the start. We'd talk daily for weeks before meeting up in person. It was like being set free; we had this instant chemistry that felt like a mix between adrenaline and comfort. After about a month, I invited them over to my place one night. It was just supposed to be a simple dinner and movie, but the mood quickly shifted. We started out slow with cuddles on the couch and some light kissing. Then it escalated. Alex mentioned they were into something called DDLG for adults, dynamic dominant-little relationship stuff. At first, I didn't really get what that meant. But when Alex said 'Can I just pretend you're my little girl?', suddenly everything felt different. I don't know where the idea came from or why it appealed to me so much at the moment, but something about it was compelling. It seemed exciting and freeing in a way that made all other inhibitions melt away. Before we knew it, I was agreeing and playfully responding with 'okay' when Alex said things like 'sit on my lap,' or 'I want you to be good for me.' The more I went along with this adult role-play, the easier it got. We ended up having some very intimate moments that night, but not in ways that were typical of how we'd acted before. There was something thrilling about playing these roles out and being completely open about everything during them. It felt like a release from reality, even though it was all consensual and adult-based. But now I'm left wondering if maybe I should have been clearer with my boundaries. I've been replaying the whole evening in my head ever since, trying to figure out what this means for our future together or whether it's best to just move on. The memory of it all feels so vivid and strange, like something straight out of a dream yet completely real at the same time. Writing this helps me feel like maybe I'm not alone in having these experiences. So yeah... that's where my mind has been wandering lately, back to this night that was both liberating and confusing at the same time. Anyone else ever have something similar happen?
