This drama follows Seino Sakura and her high school friends as they learn about and explore different issues related to dating, sex and sexuality. They comprehensively cover all those issue that a teenager might face. It is basically everything sex ed should be in a drama.

Everyone should have access to factual information, free from bias and taboos. I feel that 17.3 About a Sex does a good job in this area. It is well-made, well-researched, well-presented in a mature, non-judgemental way. Safe for young people to watch alone, with friends or with parents. I would highly recommend this.
