Drunk hookup situation?

Me and my friends went camping and I hooked up with a dude that came out to me and now I can't help it but like him. He says he doesn't remember anything from being so drunk as was I but I know you would remember something like that. I accidentally took home his sleeping bag and he is gonna come and get it one of these days and I can't help but wanna talk about it but I don't know how to go about doing this. How should I say it? straightforward? hint at it? never speak of it again? he told me he liked me so i can't just let this go.
