Is it odd to date someone three years older than you?

I'm going to be 16 in 2 months and he's going to be 19 in 5 months.
Is that weird?

He isn't actually my boyfriend yet but we've been on one date and we talk all the time.
I really like him, we have so much in common.
But he lives in Kentucky and he's going to Florida for college this fall.

Now I'm going to rant about age:

It's weird, I'm 15 and I'm going to be a Junior this fall.
I am almost an adult.
But I'm still very much a child:
I wake up early to watch cartoons,
I have to have everything explained to me,
and I am very naive.

It's weird, being a fifteen year old girl, I have dated only one boy in my whole life.
I know 12 year-olds that have had more boyfriends than me.
I'm quiet, so I typically don't talk to people on my own.

It's weird that in 2 years I will be going to college.
I will be treated like an adult and expected to act like one.
I'll be my own person. I'll be responsible for me.
I've been sheltered my whole life.
and then I'm going to have to grow up.
