Im a freshman and I really like this Junior?

my name is andria, and I really like this guy named Ty. but he's a junior and im a freshman. I know he likes me back, ive heard him talking about it. But what if he makes a move? I dont want people to think im a skank because im going out with a 16 year old! but things are just so good between us! We have soooo much in common and have not been in one fight,. PLEASE TELL ME WHAT TO DO!
