A couple things: I've never known a 19-year old who's hooked up with a 14-year old, but that would have lost you friends in a hurry back when I was that age. It won't land you in jail, but it's also not socially acceptable in most circles.
But also, what is your point even? Because our country allows up to a 5-year age gap, a 7+ year age gap should also be considered fine by everyone in the country? Why? That doesn't even make sense.
