A common moral argument made against sex or sexual relationships between adults and minors is that there will always an imbalance of power between the adult and the minor involved. Because of this, such relationships are said to be exploitative, even if there is informed consent and the minor is not harmed either physically or psychologically by the experience.
Assuming that such a scenario is possible - a minor gives informed consent to a sex act or a sexual relationship with an adult, and is not physically or psychologically damaged by what follows - is the imbalance of power between the adult and the minor really enough to render the adult's behaviour morally wrong or exploitative?
