Research: Intergenerational Relationships in History
There have existed a wide range of western and non-western societies that have tolerated or encouraged intergenerational sexuality.
Ancient Greece
Much has been written about the Ancient Greeks and their age-structured pederastic relationships. So much in fact, that we can cite Wikipedia and Truthtree as accurate sources of information in this area. To the Greeks, relationships between men and adolescent boys were not only acceptable, but a desirable form of mentorship and (military) training towards the masculine ideal. As accounts reveal, rules and regulations within this model were particularly strict - arguably more so than in modern societies that condemn pederasty as pathological.
1970s, 1980s, Netherlands
The Netherlands is a fairly recent example of a culture in which intergenerational sexual relationships were partially tolerated during a particularly liberal period of history. For some time, sexual relationships between a child above the age of 12 and an adult would remain legally immune to prosecution for as long as the younger partner, their parents or a welfare entity did not complain. Such authorities were much less inclined to lodge complaints during this period, leading to a markedly non-hysterical climate in which many such relationships succeeded. One writer to document such positive relationships was Theo Sandfort, whose most famous study remains an outstanding example of this unique period in time.
1960s, 1970s, Baltimore
During these decades, there were notable gay subcultures in America, where young boys were allowed to have sexual interactions with men with little fear of ostracism or psychological trauma. Baltimore is one often recalled example of this.
