Hi Jonas, thank you for reading this article. As far as I am concerned, the main success factor is that they use real, live models' body and tell their viewers, especially for adolescents, "you are not different and you will also experience this during puberty." Thus, the adolescents will not feel embarrassed when they face these things.
This is great! When I was doing my secondary research, I also thought of doing a small survey on some mobile apps. You can check and download the app "Juicebox" which is an app that allows users to anonymously ask questions about sex and sexual health.(even though it is not a game)
