They compelled their daughters to wear gloves made of special material called steel wool (like scourers) at night. In addition, they forced them to pour a powder on genitals that made all touches to them very painful. The boys were forced to wear at night metal chastity belts. Of course, the erection is such "clothes" was also painful. Sometimes their methods were very brutal, they new no bounds. To prevent masturbation they pieced the foreskin of their sons with a wire and soldered the ends. Thus the foreskin didn't move. Parents really believed masturbation leads to madness, illness, blindness, impotence and sexual pathologies. In our days it was already proved that it's not true.
