Argentina: 'Almost everybody here has sex at 13 or 14'
Argentina, the land of the tango, is a passionate country and, despite the strength of the Roman Catholic Church, casual sex is far from uncommon.
But the teenage birth rate in Argentina is double that of Britain, partly because abortion is illegal.
The age of consent is 13 and a doctor tells presenter Billie JD Porter: "Almost everybody begins having sexual relations around 13 or 14."
Billie also meets Palmeira, 15, who gave birth to her son a year ago. She says she got pregnant "by accident".
Watch Generation Sex on BBC Three at 21:00 GMT on Wednesday 12 February or catch it later on the BBC iPlayer.
