Even though you're just a little older than me...
I honestly suggest that you wait. I feel like teenagers these days feel a NEED to date. They just HAVE to have a significant other, and we're already transitioning into so many other huge changes in our life right now, it'd be a completely unstable decision to get a boyfriend at this time. We're keeping up with studies, we're getting prepared to graduate, finding a college if God tells you to go, to get a job if you don't have one yet...it's draining, especially emotionally. The person we date now is 94% likely not to be the person we marry. And if that's the case, then why even bother?
These are just my thoughts on it, and it's why I've never had a boyfriend, and probably won't for a loooong time. But only you know yourself well enough to say, "Yeah, I can do this." And in a way, every time I see questions like this, they in a way already have their motives set in stone and intend on doing it. So if you do, if you don't listen to anything else I say, just listen to this:
Pray. Pray for whoever catches your eye, and whoever finds interest in you. And actually LISTEN for Him. If God doesn't want you to be with that person, He'll let it be made known (it may not be huge flashing lights...it might just be a small thought saying, "You know...maybe not."). If you don't feel peace about them, then they're definitely not it. I know not everyone will agree with me on this. It's probably because they've had different experiences. And that's okay. There's no cookie-cutter way to successfully find your future spouse. Everyone's different. But it NEVER hurts to pray for whoever you're interested in or whoever is interested in you.
