I'm poly and have gone on dates here and there but never actually been in a committed polycule. To be honest I'm not looking for anything very serious, but recently I've found I have two friends who are together and poly that I've been light heartedly flirting with. I didn't want to take the first step in asking them if they wanted to have some fun and go on a couple of dates because I wasn't sure if they were looking for something casual or more serious, but then they talked to me about what I was looking for and I was honest with them. This may sound silly but I don't know where to go from here! I like them both a lot and hanging with them as a group and one on one, but I'm unsure where to go from here now that we've established interest. I know I should just talk to them, but I want to go to them with some idea of what I concretely want moving forward and honestly I keep falling short. All I can think of is just "spend time with them and have sex together or one on one" but I don't know that that's enough.
My friend, I think you are overthinking this! If you like hanging out with them, and they like hanging out with you, keep doing that. If they asked you how you felt and you told them, and they were open and receptive, let things keep going in that direction!
You are correct that you “should just talk to them,” but you are being way too hard on yourself by concluding that what you have to say is not “enough.” You know what you want - to spend time together, and to be open to sexual or romantic connection - and that is an entirely normal and healthy and common way for people to be together!
Try saying something like this:
“I really enjoy hanging out with you two, together and one on one. I know that you two are polyam, and I am thinking that I’d be interested in exploring that with you. I like our friendly connection and can see that moving in a romantic direction. I am also sexually attracted to both of you and would be interested in cuddles, kisses, and sex.
At the same time, I am feeling unsure about what I want to call this, or whether I can articulate exactly what kind of relationship blueprint I am hoping for. Are you okay with taking things slow and just letting them evolve organically the way they already have been between us?”
What you’ve described here sounds pretty healthy and fun, and is in fact how most relationships, polyam or mono, tend to evolve and grow. Follow what feels good and try to relax about the specifics.
