In today's society, there is a lot of secrecy surrounding the topic of "sex," and many adolescents have not been able to acquire accurate sexual knowledge. According to a previous survey conducted by "AIDS Concern," the infection rate of sexually transmitted diseases is higher among teenage girls compared to teenage boys. Recognising this issue, "AIDS Concern" organised a lecture titled "'Let's talk About Sex" on November 30, 2017, at The Chinese University of Hong Kong.
"AIDS Concern" specially invited renowned guest Chapman To , Associate Professor Dr. Ho Sze-ying from the Department of Social Work and Social Administration at the University of Hong Kong, and Dr. Tso Man-kit, a lecturer in Gender Studies at the Chinese University of Hong Kong, to engage in a lively discussion about "sex" and thoroughly explore contemporary social relationships between genders with over 240 university students present on campus.
