I need a song that describes me and my Boyfriend?

Im in a relationship with this guy we've only been together for about a week and we don't have a song! With all my other boyfriends it just came to me what our song was, why is this guy more dificult? A week or two ago I went to a winterjam with my friend and she was tellin me about the guy I'm datin now she said he was cute,but annoying and she had dated him before! Well after the winterjam we went back to her church for a lock in! And ever since I've been going to that church! I liked him from the first time I saw him but I didn't think he liked me I thought he liked another friend of mine! Well the other day he asked me out! And now we need a song! We are teenagers any ideas??
