Hong Kong has a new sex education guide that's causing a stir, with some people saying it's too old-fashioned.
The guide suggests teens avoid sexual activity by focusing on things like badminton, which some feel is a bit out of touch.
Government officials are defending the guide, saying it promotes abstinence and responsible relationships.
This has sparked debate about how to talk to young people about relationships and sex in a way that's both helpful and respectful.
