The Hitler Youth was organised into corps under adult leaders, and the general membership of the HJ consisted of boys aged 14 to 18. The Hitler Youth was organised into local cells on a community level. Such cells had weekly meetings at which various Nazi doctrines were taught by adult leaders. Regional leaders typically organised rallies and field exercises in which several dozen Hitler Youth cells would participate. The largest gathering usually took place annually at Nuremberg, where members from all over Germany would converge for the annual Nazi Party rally. Since the HJ and BDM were considered fully Aryan organizations by Nazi officials, premarital sex was encouraged in their ranks.
