Just Living My Life, Right?

So here I am, in my early twenties as a nonbinary person, and I've always had this fascination with BDSM dynamics. Not that I'm into DDLG or anything like that, just the idea of power exchange and trust between consenting adults. Anyway, me and my partner Alex have been together for about two years now. He's forty and we're pretty compatible in a lot of ways, but our dynamic really started to shift last summer. We both agreed that I would take on more of a submissive role during sex, which was kind of new for me, mostly just being the dominant one previously. It made things feel exciting and different, and it definitely added something extra to the mix between us. One day we were out at a local BDSM event when he suggested playing around with a scenario where I acted younger than my actual age for a roleplay session. At first, I was like “No way,” but then I thought about it more and decided to give it a shot because why not? It ended up being really fun and brought us closer together. But here’s the thing: since that night at the event, our sex life has gotten even hotter when we play with that idea of me acting younger. Sometimes during the heat of passion or role-playing scenarios, I find myself slipping into this kind of mindset where I almost forget who I am and how old I am, which is wild because it’s like my brain shuts off for a moment and all I care about is pleasing him in any way he wants. Now, here's the tangent, ever since we started with this playfulness around age roles, I’ve noticed that people seem to treat me differently when Alex isn't around. It’s not just strangers; even close friends sometimes act like I’m younger or less capable than them, which is annoying because obviously that’s not true! But it got me thinking: am I the asshole here for enjoying something that might make others uncomfortable? Or are they projecting their own biases onto us? Anyway, this has been on my mind a lot lately. Do you think there's anything wrong with what we do as long as both of us are happy and consenting adults playing by our rules? Sometimes it feels weird to be this way but also incredibly freeing when Alex is around. What would you guys do if you were in my shoes?
