Why would a guy text at 3am? booty call? But We haven’t had sex?

I kissed this guy a week ago and I texted him a few days after just to catch up but I didn’t have a reply and then Friday night 3am I received a text from him... ok probably he was expecting a booty call but he knows I won’t sleep with him. Is he just trying to get lucky?
