A Night of Unexpected Twists

So last night, I went out on a date with this girl. Not the girlfriend kind, just some casual meet-up at a cafe. Nothing really happened there, we chatted for a while and then decided to move somewhere more private. That's when things got interesting. We ended up back at my place. One thing led to another and I thought we were going to kiss or something, but she surprised me by pulling out handcuffs from her bag. Now, to be honest, I didn't see that coming. It was a little bit of a shock, but also... well, you know. We played around with them for a while, and then she suggested trying another toy. Nothing too hardcore, just something new. At some point, we talked about maybe doing it the next day again, her idea, not mine. It was all consensual of course, and I enjoyed myself quite a bit more than expected. But now here I am this morning, wondering if that's normal or if I'm just way too easy-going about it. What do you guys think? Is there anything wrong with enjoying a casual encounter like that? Or is it weird to be down for new experiences on such short notice?
