One night stand

So last night I went out and ended up going home with this guy. (I've met him a couple of times, friend of a friend) and he said he wanted to get to know me. Thing is, he's not messaged me and I don't know if I should message him, and if I do what do I say?

Or should I just let it go🙊😂

EDIT** We didn't end up having sex, and I stayed and chilled with him this morning
