Synopsis

In 20XX, humans are on the verge of extinction. Due to low birth rates (especially for boys), the current male-female ratio is 1:10721. The world leaders decide to pass a new law to combat this crisis: The New Sex Law. All males receive a card called the “Free Sex Licence” which allows them to have sex with any female once it is shown. Obviously, there was much opposition to this and the results were very disappointing. To reduce the loss of vital sperm, a series of rules were imposed. Among them: no masturbation, no birth control, no non-vaginal sex. Will these drastic steps save humanity?
