Less communication after we had sex! 😳

So I went on a wonderful date with a guy and we just ended up making out after dinner and after I showed him my art. And he had asked me to see him Friday for another date so I agreed and during that week we were texting and snapping all the time! We had a great and an unexpected overnight date and we had a lot of sex. He loved it and so did I and I am starting to fall for this guy! But after our date he wasn't as responsive to my texts or snaps until the next day. He still hasn't totally communicated with me much since then and I don't know if I should just give it a few days or what? I'm sure this is common but I don't know what move to make next.
