How can I establish a friendship with someone I met at a bar?

My boyfriend and I (young gay couple) started talking to someone at a gay bar last night in NYC where we live. He turned out to be really cool and funny and had some interests in common with us. I was really pleased – I’ve been feeling like we need to expand our social circle and make some more cool gay friends in the city, and my boyfriend and I have been talking about how we’d both like that. We exchanged numbers with this guy at the end of the night, and I’d like for us to hang out again. But I’m not sure how to go about making that happen. Of course, I could just text him the next time we go out, which will probably be in a week or two, and see if he wants to meet up for a drink or something. But I feel like it could seem a bit out-of-the-blue to suddenly here from someone you met at a bar a week or two earlier asking about getting together. There’s also the issue that it might come across more as flirting than as a friendship overture (this is concern is somewhat reduced, but not completely eliminated, by the fact that he knows we’re a couple). Another alternative would be to text him today or tomorrow, maybe referencing something funny from our conversation, but I worry whether that could come across as weirdly desperate or just cheesy (“It was great meeting you, blah blah blah…”). Any ideas for how to increase the likelihood that this could turn into an actual friendship?
