I would agree w/ the other posters. Think of the long game.
If u are 17, your body and brain have not fully developsd yet.
If she's 14, the same, though women physiologically mature faster than men
Think of social norms. This ain't the cowboy days and ur not being forced into a shotgun wedding.
Think of the law. 16 or 18 is the youngest one is legally allowed to marry in most states.
How are u going to support a family?
Getting married is good. Having a plan is good. Waiting is good.
Have u prayed about it?
Do u have a way of support?
If u ever want to run for office, u need to be squeaky clean.
Pray. Follow the rules. U'll be ok.
