Mexico City's Annual Sex Expo is the largest of its kind in Latin America and one of the largest in the world. When the first edition drew 80,000 visitors in 2004, it prompted howls of outrage from the Catholic Church and conservative groups. But today, the scandal has died down. The expo’s success has to do with "the end of the silence surrounding sexual issues, which is a healthy process seen in Mexico in recent years," says sexologist Eusebio Rubio, president since 2005 of the World Association for Sexual Health. During the expo, women and men can audition for porn flicks. The finalists will produce a film in just eight hours, to be shown on the expo’s web site. According to unofficial estimates, the porn industry in Mexico takes in around one billion dollars a year, despite a thriving pirate video industry, reports banderasnews.com.
