Just remember Logan429, once you have found that right one for you, you will be stuck with them for a long time if not forever. I know that sounds like a great idea and it is, but your still very young and you have got a lot of growing up to do, so don't feel like you need to rush into a relationship just because you have found a girl you like. There are going to be other girls in your life that you will also find attractive. Now, if you really like this girl and want to ask her to be your girlfriend, then by all means go for it! Odds are, she probably likes you too.
And whoever says your too young is wrong. Your a teenager for god-sakes, live these years to the fullest, have fun dating other girls, listening to load music, and having SAFE fun with your friends, and all at the same time, doing well in school. Your only a teenager once, let these years be something you can remember for the rest of your life.
