<human>: Give me the gist of the text in a nutshell

Hey everyone,

So I have sporadically hooked up with a mutual friend over the past year. Neither of us ever makes great effort to get together but rather sometimes find ourselves with each other if we run into each other at a party or something.

Last weekend we hooked up but this time it was different, it felt like we were a lot more intimate (in an emotional way). I kind of want to make this a more regular thing but I'm not really interested in trying to have a formal relationship.

What would be a good thing to say to see if he's interested, without coming off like I'm trying to make a relationship a possibility?
<bot>: How do I let a sporadic hookup know I want to make it a more regular thing without coming off like I want a relationship?
