In George Orwell's novel 1984, an organization for young people that advocated complete celibacy for both sexes. The Party intends to abolish the institution of the family, so all children will be the products of artificial insemination and grow up in public institutions. Members wear red sashes around their waists. Julia, Winston Smith's lover, is a member of the Junior Anti-Sex League, though she does not share their ideals.

By extension, the conservative & repressive forces in society that support ideals of celibacy, virginity, purity, etc.
"Damn, those Taliban, they're just like an Islamic Junior Anti-Sex League!"
