Emanuelle and the Porno Nights of the World (1978)

Emanuelle hosts this peculiar sexploitation Mondo film that looks at several examples of bizarre sexual behavior. Opening with a sexual mystic ceremony, it moves on to views of modern night club, including a woman trying to seduce a mule into bestiality. An unorthodox penile enlargement operation is shown, plus lesbian sex championships.

Outside of the modern world, there is footage of a boar slaughtering in New Guinea interspersed with scenes of sex. Like many Mondo films, most of this footage is staged, but still provides a fascinating view into Italian exploitation cinema.
