Bad idea. I recently heard an upper-classman guy say to his friend, "We already got all the senior and juniors. Let's go de-virginize the freshmen and sophomores." Granted, not all older guys are like this. But plenty of them are. They'll act all nice and flatter a girl with their attention. But they'll just wear down her innocence and leave her.
The younger girls often are naïve enough to think that the guy is going to stay faithful to her for the next four years as he goes off to college. For some reason, the freshman girls rarely ask themselves, "When he meets all those college women next year, is he still going to keep perusing a high school sophomore?" If he does, then he's got some serious issues.
A young girl may get all excited that an older guy likes her, but she doesn't have the backbone to turn down his sexual advances. Usually, she ends up getting burned because she's trying to look for the love that her dad never gave her. The girl thinks she's really special for dating such a mature guy, but in reality, if he was so mature, he'd be dating someone his own age.
If you want to date a guy four years or older, wait until your twenties.
