19 year old woman dating 25 year old man?

I recently turned nineteen (freshman in college) and I'm interested in a man who is about to turn twenty-five. Is nearly six years too much of an age difference? For reference, I'm not the flighty type - I would be ready to settle down and marry in a year or two, if it worked out. (I would still finish college, though - scholarships are paying for it and I live off campus already anyway). Would it be worth it for us to consider dating?
