The 2010 curriculum includes discussions of homosexuality in Grade 3, puberty in Grade 6 — with masturbation as a possible topic — as well as information about sexually transmitted infections and delaying sexual activity, in the Grade 7 curriculum. Oral and anal sex could be discussed in Grade 7 as well.
中文翻译的夸大其词了.我觉得3年级和6年级的课程没什么问题.7年级尺度大了点,不过也是说的could be.
