Afshin Shahi in Foreign Policy:
When someone mentions Iran, what images leap into your mind? Ayatollahs, religious fanaticism, veiled women? How about sexual revolution? That's right. Over the last 30 years, as the mainstream Western media has been preoccupied with the radical policies of the Islamic Republic, the country has undergone a fundamental social and cultural transformation.
While not necessarily positive or negative, Iran's sexual revolution is certainly unprecedented. Social attitudes have changed so much in the last few decades that many members of the Iranian diaspora are shellshocked when they visit the country: “These days Tehran makes London look like a conservative city,” a British-Iranian acquaintance recently told me upon returning from Tehran. When it comes to sexual mores, Iran is indeed moving in the direction of Britain and the United States — and fast.
Good data on Iranian sexual habits are, not surprisingly, tough to come by. But a considerable amount can be gleaned from the official statistics compiled by the Islamic Republic. Declining birth rates, for example, signal a wider acceptance of contraceptives and other forms of family planning — as well as a deterioration of the traditional role of the family. Over the last two decades, the country has experienced the fastest drop in fertility ever recorded in human history.
