19 and never been kissed ):

This feels like such a stupid problem. But I started seeing this guy and I really reallyyy like him. But the issue is that I've never been kissed and he's tried to kiss me once before but I panicked and told him that idk what I'm doing and he told me he'd wait until I was ready. And I am ready, I just don't know what to do with my lips?? Does anyone have any tips because i really don't want to be bad at this. And I know we all start somewhere but I'm just so nervous 😬😬
