A racy documentary about the female orgasm offered on Qantas flights could have many passengers squirming in their seats.
French-language film The Female Orgasm Explained features old porn clips, naked scenes and women kissing.
Originally shown on Australian network SBS, it aims to help viewers understand the mystery of the female orgasm through the eyes of eight women aged between 24 and 68.
The 48-minute film is rated MA (mature audience only), for viewers aged 15 and older. But it is available on all international flights as part of the in-flight entertainment programme.
Qantas spokesman Luke Enright said the film was the most popular on its television channel The Edge and would continue to be screened until November.
