Pervs will be pervs. Sexually repressed individuals. Often become abusers.
So early marriage as well muta (temporary relationship including sexual) seems to be good solution for me. Emphasize to get married early in life or if you can't do that, do Muta the way Quran teaches. That way if kids are born, they know their father and there is no shame to them, and they are under responsibility of parents.
A society that doesn't mix purpose with sex, is going to debauched and they will abuse children.
