The Last Man on Planet Earth (1999).

When World War III begins with a war in Afghanistan, an incurable biological weapon called the "Y-bomb" (targeting Y-chromosomes) is used killing 97% of the world's men. Feeling that they are better off without men, the planet's women decide to outlaw men because they were too violent. As a result, cloning has become the principal meaning of reproduction, with lesbianism becoming the norm.
Years later, scientist Hope CHAYSE, fearing for the future of the species, conducts a cloning experiment to produce a new male, Adam. When he reaches maturity, he soon finds himself on the run from the FBI, hiding out with small rebel bands of the last surviving men on Earth.
Of particular interest, at 4Ø minutes there’s an extremely curious scene; Adam has been sold to a brothel, and his first client wants him to slap her around. Don’t believe me I really don’t give a fuck; Skip to that point and watch it yourself.
