It's been two days since we talked should I move on?

We had our second date on Friday, I texted him on Saturday to say I had a great time to which he agreed and suggested a next time. I have to add that we had sex that night...
I like him a lot and want to continue seeing him, but now I'm worried he doesn't want that since we used to talk almost every day and now silence... and I don't know if I should wait or move on?
