Guy that I’ve been seeing for a month texted me that “I’m literally all yours”?

I’ve been going out with a guy for a month and yesterday we were texting to figure out our weekend plans and he said “I’m literally all yours.” I haven’t responded yet because I like him, but I’m not there yet. What should I say?
