In my opinion, I believe if you had such a good time you can keep talking you him. Get to know him better and try spending time with him. You can also let him know that you had a wonderful time on your date and that you are looking forward to other dates. If you are not shy, you can also ask him out.
Wait for him to call, or text. Don't ask him out, wait for him to ask you out. Then you will know if he's interested. Don't scare him Away and don't discuss it with anyone until you know for sure your answers
