I actually remember being in that situation at school. I had a crush on this older girl, had no experience with girls. I never spoke to her. I look back now and laugh at how dumb I was. If I could go back to that time would I approach her? maybe. But before that I would be trying to make an effort with the vast amount of other girls that I overlooked. Trust me you will regret not getting the experience when you had the chance!

Maybe one day she will become single and you will have a reputation as more of a ladies man. But for now dont waste your time on one girl who you dont even know!!!
