I read a non fiction book about 10 or so years ago that claimed that in some tribes in 0 AD Britain it was common for mothers to introduce their male children to sex by having the first encounter with them. They then went on to marry and reproduce as normal.
My questions, is this recorded or accepted widely by scholars of the time? if so what evidence is there for this? Secondly anyone know the title of the book I read? I lost it many years ago, the title was something like “Britain Zero Ad” but google searches come up with naught except for references to Khmer Rouge Year Zero.
