Futari Ecchi: Doing What Too Many Other Won't
Whatever you just saw happen in that anime/manga, don't try it in real life.
Don't try to catch a blade with the palm of your hand, or spin the ball on the net while playing tennis, and don't try basically anything you see in any ecchi manga.
In regards to romance manga, most "tips" and "tricks" displayed will do nothing.
However, Futari Ecchi is different.
Whatever it says is most likely accurate, and most of its tips are recommended.
You see, Futari Ecchi is not just an ecchi manga that shows boobs and butts and people accidentally slipping inside of each other (though...it does happen once or twice in this manga as well). It's realistic and descriptive and, most of all, educational.
Following the daily lives of Makoto and Yura Onoda, a newlywed virgin couple, will teach you a lot. You learn about the statistics of marriages such as theirs, what kind of roles people tend to assume/expect, and (a little more...applicably), a lot about sex.
This manga doesn't hold back or shy away, ranging from the intricacies of affairs to proper blowjob techniques. It addresses the stigmas of hymens and their meaning and the benefits of masturbation for both males and females.
All of this knowledge is distributed through an amusing story and likable characters.
Makoto, a clumsy businessman, is plagued constantly by women of all types for the first time in his life. Though tempted, and often full of (very detailed) fantasies, he stays faithful to Yura every day.
Yura spends her days taking care of their home and often meeting her sister Rika and other friends, each of which provides their own lessons.
Rika, as a VERY experienced and promiscuous young woman teaches Yura how to have safe sex on her period, and how to perform blowjobs, and several other things.
Makoto's cousin Kyoko, an OBGYN, teaches them all kinds of medical facts, and when they attempt to conceive a child, offers her advice there as well.
Makoto's brother Akira preaches the importance of foreplay to his inexperienced brother, who had basically been just shoving himself in for the first few times he slept with his wife.
Most of these lessons and fantasies are accompanied by vivid scenes of people having sex, although it is censored to not show the naughtiest bits. In fact, in scenes focusing on the penis, it's often replaced with a banana.
A banana which is then sucked and licked and played with, but still a banana.
Over the 69 volumes (yes, there are 69 so far, meaning any more volumes are a bittersweet victory) available so far, a person can learn and explore with Makoto and Yura, laughing at his stupidities and minor misfortunes.
And in countries such as Japan and America, the two largest buyers of this manga, this is important. Too much is unknown and discovered too late, and Futari Ecchi works hard to end that.
