I'm in an ethically non monogamous relationship. We don't really talk about it with others but are open to threesomes (I've never discussed any of this with this person).

I've always had a little crush/attraction to a male friend who recently started sending me reels and tik toks about an inside joke we have. Recently, he sent me a funny tik tok (totally unrelated to anything we've ever joked about) about someone on a dating app sending a match a message that made them think they were a swinger. I laughed about it even though it was so random.

We then went back to talking about our usual inside joke and sharing an item related to the joke. He then asked me if I was "ready for that type of arrangement?" In reference to this item. But the language feels loaded given the previous message.

Is this person flirting with me or insinuating something? I haven't had to decode a message in so long. My partner seems to think he's flirting with me but jury's still out.
