Hung(2005)

Living in a world that seems rife with phallic symbols, five lesbian friends take a teaspoon each of a concoction from Prague that will give them, for only one day, a penis. Next morning, the cock crows and the women seek men's experiences: they measure and compare, pee standing up, and look for women who'll sleep with them. At the end of the day, they gather to compare scores. It's a jungle out there.
