You are right. This kind of premature sexual engagement is severely damaging to the normal development of attachment in young males. Years before it became fodder for the evening news, mental health professionals understood it. They called it hyper sexualization. The effect is promiscuity, and it shows in female as well as male child victims.
It is the reason why young teen males in the inner city go around spawning children indiscriminately and without any sense of responsibility.
