Are boys psychologically harmed by sexually expressed relationship with older males?

A cardinal assumption of victimological dogma is that sexual contact between a boy and an older male causes psychological harm that is pervasive and intense. If a boy is forced to do something he does not want to do, it seems reasonable that harm would ensue. But there are many studies that document willing participation, a lack of such harm, and/or positive benefits. Here are a few:
