It's not deemed wrong by the law if that person is a legal adult. As to whether it is morally wrong, that's somewhat subjective. There is no consensus. People might question what you would have in common with someone of so many years younger than you and they also might question why you are interested in youth above all else. Furthermore, the younger person may have no interest in being with someone your age regardless of what you might want.
