Can someone please explain how do everything with my lips/mouth?

I've been avoiding kissing for about 3 years now because I was scared it would be bad. It was bad, worse than I thought. I was disappointed and embarrassed.

I had my first make out today, she slipped in tongue and I was confused, we were completely out of sync, our lips weren't going the same time. I think I missed her a couple of times. I tried again and again then finally she said, "I don't think we should kiss right now, maybe next time" I sort laughed, said why lol while laughing.(please tell me what I should say here) and took her to the back of my car, kissed some more and did some kino, eventually one session/cycle worked out well..but still not great.

During this whole thing she repeated this move where she would start pushing her lips foreward and more strongly aggressively towards me and then stop and push out quickly .....what does this mean? I'm guessing she wanted me to be more intense but I wasn't. She slipped in tongue several times but I had no idea what I was doing.

In the car I did some kino but couldn't do much because of our positions, often times she would start shaking and breathing heavy and was very turned on(despite my awful kissing). I avoided kissing. I tried to kiss her neck but then I realized I have no idea how I'm supposed to do this.

  • What am I supposed to say at my awful make out skills? Was I incorrect to not acknowledge it? Should I let her to lead the way? How do I pull this off?

  • What did her pushing towards me mean like that mean, what am I supposed to do?

  • Someone show me with a video, or with an explanation what I'm supposed to do with my lips and tongue and how this all works. I've read descriptions before but it was completely different doing this.

Thing is, I'm 21 which makes it embarrassing.

I have NO idea how this works with my lips and tongue, it was bad guys, I was doing all the right things with my hands, one on her waist pulling her in tightly and the other on her neck. It made me feel bad about the whole date. I had no idea what to say after.

I'm embarrassed.

fortunately she wants another date.

Edit: may someone please answer the questions in bullets?
