To be honest, the only thing bothers me is that my friends act all immature around a girl, and usually get me into trouble. I don't like it, and plus, the couple don't like it either. Probably until I'm in college, I believe their will be some better, more mature friends that I can hang around with. My friends just show their immaturity since they can't get a girlfriend or probably can't stand near one, it's just plain dumb.
I for one don't have a girlfriend, and probably won't until I get older. I believe it's best to have a more, focused mind whilst you're going through the worst (Like exam stress, Coursework etc.) after school since it's usually more important to be focused at that time. Then around when you're in University or in a job, you can start a relationship up, I mean, it's more of a right time to do it, and you're old enough to enjoy yourself even more.
I think that's what most people do, even though they might be in a relationship, they would focus more on their future, rather than their relationships.
