Your notion of morality in this case is an arbitrary and artificial construct that you have been conditioned into believing. Other than the past one hundred years or so, for all of human history it has been legal to engage in sexual intercourse with those who are not prepubescent. In much of the world it is still legal to engage in sexual interaction with those who are 13+ or 14+. We have been evolutionarily programmed to find 14-17 year olds sexually attractive, with the exception of the past one hundred or so years it has always been considered morally acceptable to have sexual relations with 14-17 year olds, and in the majority of the world it is legal to have sexual relationships with at least some segment of the people who fall between the ages of 14-17. Indeed, in several parts of the world it is legal to have sexual relationships with people who are below the age of 14. Only a tiny fraction of the men arrested on To Catch A Predator would have broken any laws if they lived in Spain, even living in Eastern Europe or much of Western Europe would have spared many of the men. In some parts of the USA men are labeled as sexual predators for engaging in behavior that is legal in other parts of the USA!
