The Night We Broke All the Rules and Had Fun

I'm in my mid-20s, nonbinary, and I've been in an open relationship with Alex for about a year. We have agreed upon mutual trust and respect for boundaries, which has led to some incredible experiences between us. However, last weekend, we crossed into uncharted territory that left me feeling both exhilarated and a little unsure. We decided to visit a swingers' party together. I felt anxious beforehand but excited too; this was something neither of us had ever tried before. We met other couples and individuals there, everybody seemed so confident and at ease, like they were old hands at the game. Alex encouraged me to step out of my comfort zone and join in. As the night wore on, I found myself becoming more adventurous. It was a whirlwind of conversations and laughter with strangers-turned-acquaintances. One couple invited us over to their apartment for drinks, turning what had been a public event into something more intimate. That's when things got even more interesting, and complicated. In the bedroom, we met another couple who seemed intrigued by our dynamic. They suggested trying out an arrangement where they would take turns with Alex and me separately. Initially hesitant but curious, I found myself caught up in the moment, enjoying the connection that formed between us despite the unconventional setup. The next day brought a different mood; I woke up feeling exhilarated yet questioning my actions. Is it normal for people to enjoy experiences like this? Am I an asshole for participating without fully knowing everyone involved? How do we navigate these complex feelings moving forward in our relationship? I appreciate any insights you might have about exploring new territories in relationships or what healthy communication looks like post-swing party.
