The Final Member (2012) online

Thirty miles from the Arctic Circle, in the northern Icelandic town of Husavik, stands the Icelandic Phallological Museum - the world's only Penis museum. Over 40 years, the founder and curator has collected every specimen from every mammal except for one elusive penis needed to complete his collection: The Human Specimen. The film follows the curator's incredible, sublimely comic, often shocking quest to complete his eccentric collection, and the two intrepid men who have raised their hands to be the first human donor.
