Advice for dating

I’ve been talking to this guy for a few weeks. Last week we had hung out for the third time with some friends and we ended up doing things after going to the beach. I had a good amount of drinks so that’s why things happened. I had even told my friend I wanted to make him wait a little bit. I might be hanging out with him tonight but I don’t want him to get the wrong idea about me. I don’t want to be a friends with benefits thing or someone he just calls when he wants something. How do I tell him that without him judging me because of what happened last time and what if he expects it now? I actually like him but I’m nervous to really say anything. Please any advice would be amazing. Thank you :)
