My Secret Kink Experiment

Hey there everyone! So I've been in a relationship for about three years now with my partner, Alex. We have an amazing connection and are pretty open with each other, but one of my kinks has always felt like it was on the edge of what we'd do together, specifically, I really love being tied up during sex. It's not something I ever mentioned to Alex out loud before, and truthfully I didn't think he’d be into it or vice versa. But recently, I finally worked up the courage to tell him about this desire of mine while we were having a casual conversation one night at home. To my surprise, Alex actually thought it was pretty cool and kind of hot! We decided to give it a try during our next private session together. It made everything feel extra intense and added an element of trust that I hadn't anticipated. So here’s what I'm curious about: how do you guys balance having different kinks in your relationships? Any advice for keeping the lines of communication open when introducing something new like this?
