Sex has long been a taboo subject in local schools. Embarrassed by the sensitive topic, teachers and parents shun open discussions about sex with youngsters. With interactive displays and lively dramas, the annual Sex Cultural Festival is aimed at encouraging people to talk about sex in an open way. Jointly organised by the Hong Kong Sex Education Association and Family Planning Association, the festival invited universities from Hong Kong and Macau to stage booths where everything from ancient sex art to modern sex toys are on display. With the Chinese University embroiled in a controversy surrounding its student newspaper, editorial members from the publication were also invited to set up a booth at the fair. Sensitive topics, such as homosexuality, sex change and sado-masochism, are also covered in lectures. The organisers hope young people will find the fair inspiring and develop an open mind towards sexuality issues. 'Young people often feel puzzled about sex,'' said Grace Lee Ming-ying, education officer of the Family Planning Association . The fair is held at the pedestrian zone along Chater Road in Central until tomorrow.
