First off, let me say congratulations. Your first kiss sounds like it was wonderful. I can tell you from experience that you will remember that first one for the rest of your life, so I am happy for you that it was a good and sweet one.
I, alas, was more of an early bloomer in that department, but I am taking the liberty of sharing my cousin's story, just because it was so fun to see the results.
My mother had to go out of town, so she got my cousin, who was 24 at the time, to come and stay with me while she was gone. My cousin is a really big girl, and she's kind of plain, so she never ever dated. Just before she came to stay with me, she was set up on a blind date by a friend, and she met this really nice guy who was only slightly more experienced than she was. She had asked my mom if it was okay to have him over while she was gone, and my mom was so delighted she immediately gave her permission to have him over every day if she wanted to.
This was back in the stone age, when few people had VHS players, and we happened to have one. There was exactly one video store in our area, and it was this tiny mom and pop operation--I would guess they had about 200 titles in their little tiny store. My cousin is a really good cook, so every night she would cook a delicious dinner and then she and I would watch a movie. Her guy was taking night classes as well as day classes, so he would only come over about every third night to join us for dinner and a movie. They were kind of nervous about being alone, and every time I would try to excuse myself to go to my room to do my homework one of them would say something like, "Why don't you do it here in the family room? The light is better/the desk is bigger/the reference books are out here/etc..." So I would sit there and do my homework and try to ignore them while they sat on the couch and watched TV or another video. I remember they wouldn't even hold hands--they would put their hands down side by side so they were touching, but they were even afraid to hold hands.
One Friday when she came to get me from school we hit the video store and got a copy of the Zeffirelli version of "Romeo and Juliet". She decided on the spot that we'd call her guy and have a themed night with spaghetti and meatballs and the movie. It was a nice evening. About 20 minutes before the movie ended (I had already seen it a bunch of times--it's one of my faves) one of my friends called me on the phone, so I went into my bedroom to talk. I got done, and was coming back out to the family room when heard this really funny snuffling sound and a gentle voice saying, "Oh honey, don't cry. They're together in heaven now." I walked around the corner and he was holding her face and they were really close. They were so in to each other they didn't even notice me, which was good because I was so surprised I was frozen in place. As I watched, he gently kissed the tears away from each of her eyes, and then hesitantly moved down to her mouth. It was all in slow motion, and I was fascinated. Luckily, I came to my senses and quietly left the room.
Like ten minutes later he came and knocked on my door to say goodnight, and I tell you, the guy was floating. He had this spacey look in his eyes. He was trying to put his gloves on his hands and it wasn't working because he was trying to put them on the wrong hand, which I gently pointed out. I helped him with his gloves, and with his coat, which was buttoned incorrectly so it was hanging completely askew. He went back down the hall and she let him out and locked the door. She had the spacey thing going on, too. She just had this totally vacant look in her eyes, like she was on the most powerful drug ever made, which in a way she was. She sat down on the stairs by the door and just sat there. I went to bed right after that and when I got up two hours later to get a drink, she was still sitting in the same place, only with her fingers on her mouth. She was just goofy with it all. I had to take her to her room and get her PJs out of the drawer for her, tell her to wash her face and brush her teeth and get her into bed. It was hilarious.
The next morning I woke up and there was a note saying she was making French toast for breakfast, but we needed eggs, so she had run to the store really quickly. I started to get out the skillet and stuff. Suddenly she comes walking in, and to my surprise, she still had her PJs on! She had managed to get shoes on, only they weren't a pair. One was a sneaker and the other was a snow boot. She just sort of floated into the kitchen and then looked at me and said, "I'll fix breakfast alone today, come back in ten minutes." I figured she wanted to be alone with her memories.
It was a very memorable breakfast. Along with her freaky clothing, the orange juice had been made with milk instead of water, and the eggs for the french toast included huge chunks of eggshell. She was still so loopy from her first kiss she didn't even realize what she'd done. She was just sitting there staring out the window. I finally got up to make a new and improved breakfast, and she sort of snapped out of it long enough to notice that it was all messed up. Finally she blurted, "I had my first kiss last night! Have you ever been kissed? It's the most amazing thing in the world!" I agreed with her that it must have been pretty amazing, seeing as how she'd gone to the store in her PJs, made orange juice with milk in it, and put the entire eggs in the French toast. She was momentarily horrified, and then we started laughing like loons.
After that, during the remainder of my mom's trip, I was allowed to do my homework in my room ;) They got married about four months later, and now it's 25 years and four boys later for them. They're still nuts about each other. And me? I will never forget how that first kiss for them put them both over the moon. It was a really neat thing, and I am glad I was there to witness the result.
