Yumeji has a big problem, and no, it's not that he's gay (for now, anyway). Despite his good looks, excellent grades, and talent for sports, he's not getting any, and it has everything to do with the fact that he's impotent thanks to a traumatizing event back in middle school. Nothing seems to help, and since Viagra is apparently not a viable solution in Japan, he's practically lost all hope—until he meets underclassmen Seiji, who's violent, tactless, and says whatever is on his mind. Conveniently enough, he's also in love with Yumeji.

So what can you find in an average yaoi manga? Fetishes? Girly uke? Masculine uke? Aggressive seme? Shy seme? The deed? Impotency? Bishounens? Love?

If you asked me what has made me to love yaoi more, I would straightly answer Otona Keikenchi. The one who has got me in its sway. The culprit for this obsession.

Frankly speaking, Otona Keikenchi is one of the freshest manga that I have read in this genre regardless of the cliche plot. Not because I have it in my faves but on the grounds that it's peculiarly entertaining.

The story progress isn't slow nor fast paced. It simply starts off with Yumeji read more

I'm not entirely sure as to why I chose this manga to review instead of an actually good one.

Story - 4.

I wouldn't say that this manga is an entire cliche, but I would say that it is all over the place and disorganized. There's also unnecessary drama (yes, BL is filled to the brim with it, but this BL is filled with it and more). At one minute, Yumeji is talking to his bisexual posse (I wouldn't be surprised if they had matching jackets with huge un-ironic dongs on them). At another minute, Seiji is telling Yumeji that he read more

hmm just reviewing, i think otona keikenchi is the best yaoi manga ever. i'm not saying high, the art is very good, and the story isn't mainstream. You know, girly uke, or seme is tall, is too mainstream. In Otona you can find uke with cool face and its my first time to read yaoi manga which seme has cute face and shorter than his uke. So i recommended you to read this manga.

Fluffy school story between a older and taller glamorous bishie uke senpai and his pushy pint sized seme love interest. You can probably already guess that the above pairing is not one of my favs. Despite all that I still pretty decent and I enjoyed the art.

But to be honest, Yumeji was so hot and adorable I spent most of my time reading it wishing a more traditional seme would come and claim his ... heart. lol

Manga: Mousou Elektel
Same author and same art style. Both main characters tends to reject the fact that he is feeling attached to someone of the same sex.

It has a good plot like Dekiru Otoko. Though there is a lot of drama.

Both manga have characters that are obsessed with the others smell and or perfume. Not to mention they both have really pretty and cute art.
