 Criminologist Ronald Flowers writes that prostitution of children and child pornography are closely linked ; up to one in three prostituted children have been involved in pornography , often through films or literature . Runaway teenagers , he states , are frequently used for " porn flicks " and photographs . In addition to pornography , Flowers writes that , " Children caught up in this dual world of sexual exploitation are often victims of sexual assaults , sexual perversions , sexually transmitted diseases , and inescapable memories of sexual misuse and bodies that have been compromised , brutalized , and left forever tarnished .
