SECURITY concerns have forced a Chinese sexologist to drop his plan to bring a former Japanese porn star, who is also an anti-AIDS activist, to speak to his class of about 300 students.

    Peng Xiaohui, a 54-year-old professor at Wuhan-based Central China Normal University, had planned for Hotaru Akane to be a guest speaker at his Introduction to Sexology class today.

    Akane, 29, retired from the adult film industry in 2008 and now serves as an AIDS-prevention ambassador for the Taiwan-based Red Ribbon Foundation, which promotes public awareness of HIV/AIDS.

    Word of her planned visit triggered a flurry of interest online.Thousands of students from the university and other universities in the city said they would stand in line in the early hours tomorrow to secure a seat in the lecture hall for the 8 a.m. appearance. But Peng said such an unexpected and huge crowd had led him to cancel his plan due to security concerns.

    Akane’s agent contacted Peng via microblog about six months ago, “asking whether we could work together to promote AIDS awareness in China”, Peng said. (SD-Agencies)
