So me and my boyfriend have been dating for a few months. We both met on Tinder while we were in our "fuckboi era" and we both fell hard for each other. Both of us are obsessed with each other and very very much in love. Initially we would joke (kinda) about bringing a third when we were more comfortable. We have an amazing sex life and everything is fuckin amazing except for one thing.
I'm bisexual, but haven't ever really dated someone who is AMAB before. Never really been with one either. My boyfriend is trans, and I've only ever been with AFAB people before. However I recently got a toy for the first time and have discovered that I really enjoy that kind of play. We tried pegging and everything and it was fuckin great. But it has my curiosity at its peak. I want to know what it feels like with someone who has a real dick. I wanna try out sex with an AMAB person.
I don't know how to approach this conversation topic with him. I've never been in a really sexually charged relationship before this, so I don't really know what I'm doing. How should I approach this in a way that doesn't make him think I'm getting bored of our sex life?
TL;DR: My trans boyfriend [21TM] and I [19M] recently tried pegging, and now I'm curious about what it feels like to get fucked by a real dick. How do I go about talking about changing our relationship to being more open, without him thinking I'm just getting bored of him?
