What about the recent scandal on Pitcairn Island? Evidently it had become traditional for young girls to be "broken in" sexually by the mature (in age, at least) men in the community.

Pitcairn tradition

A succession of British administrators appears to have turned a blind eye to Pitcairn's customs for years, not acting when island girls had babies from the age of 12 (there was a widespread, if misguided, view on the island that this was the age of consent). No formal complaints were made until the arrival of English police officer Gail Cox in 1999. This year's trial of seven Pitcairn men tells only part of the story. Another six Pitcairn men now living in Australia and New Zealand are expected to go to trial in Auckland next year. Furthermore, 17 additional men were named as abusers during the investigation but will not be charged either because the women did not wish to pursue them or because they have died. Some women who made allegations withdrew charges after facing intense pressure from their families
