What to get my special guy for his birthday?

Okay, this guy Steve and I are NOT dating but we have this "thing" going on, And it's very serious so basically dating without the label. It's early in our so called "relationship" And his birthday is coming up soon but I don't want something that says I love you but something more along the lines of I like you ALOT. By the way Im 17 and he's 17 turning 18.....Any ideas?
