Futari Ecchi is undoubtedly the most informative and educating manga out there. However the information provided is on ‘sex’. The story revolves around the sexual life of a married couple. Lives of their friends, co-workers, family members and neighbors are also covered time to time.
Because of the extra focus on sexual aspects, this manga gets blames like ‘a series that only revolves around the bed’, ‘series with zero plot development’ etc. These acquisitions are quite wrong.
Despite being quite slow, there is quite decent plot development in this series. And we also see that the sexual aspect of life is just not only about ‘the main thing’ but the things like problems and hindrances in sex life, marriage v/s single relationships, multiple sex partners, pregnancy etc are also important part of a sex life.
We also see other aspects for a married life time to time in this manga.
