And I am not joking when I tell you that, even now, many university students believe babies come out of their mothers’ tummy buttons. China started sex education in primary schools in 2002. I was curious to know who the first group of teachers would be. I was told that some were politics teachers – that is very good, I thought, at least students won’t take long to learn about sexual politics once they’re teenagers. Some were sports teachers – that is not bad either, I thought, I could see the link between sport and sexuality, and there’s a poetic link in Chinese culture. But some teachers were made to do it as no one else would take the job.
