Is it bad?

I'm 19, I know, I'm a teen but in all honesty I'd like so adult opinions and such. I've tried to be interested in guys and girls my age but it just doesn't work, I seem to like people in their late 20s, early thirties. I find them more attractive and the fact that most people at that age is more stable, more mature ( i know that's not always the case but I hope you get what I mean). I'd just like some opinions on how that looks, I really have tried to like people my age but it's never worked out and I feel like I'm not in the right relationship. I'd like a man who has a place or is willing to save for one, settle down and start a family.
