Proud of My Poly Lifestyle

I'm a trans woman in my thirties and I've been in an open relationship for about two years now. My partner and I both love the freedom it brings us, allowing us to explore our individual kinks and fetishes without feeling like we're betraying each other. Last night, after coming home from a date with another guy, I decided to experiment with something new, roleplaying as his girlfriend's younger sister while my own partner was on a work trip out of town. It involved pretending to be much younger than I am and it felt exhilarating to step into this playful, imaginative scenario. My date had prepared a series of handcuffs in different colors, each representing a different level of restraint and submission I could choose from during our time together. We started off gently but quickly escalated, with me being bound by the red cuffs before eventually moving onto black ones as we delved deeper into my fantasies. He guided me through various sexual positions while keeping me restrained, which heightened every sensation; my body felt incredibly responsive and aroused in a way that was both thrilling and humbling. It's not just about the sex though, it’s also about being able to trust someone enough to explore these sides of myself safely with them. My partner knows what I'm up to because we communicate openly, but even with their support, I still wonder if this is too much or if others have similar experiences that they don’t share for fear of judgment.
