I mentioned Words Worth. Hentai that can do without the scenes is rare. And last I checked, girls can watch hentai and get off on it too...
At least, I hope they do...

One True Stories has an h and non-h release but the hentai version of it brought tears to my wife's eyes. I thought the ending was quite emotionally well brought about too...
Lumping all hentai together as mindless masturbation material is just as ignorant as throwing all anime into 'cartoon porn' as some 'well educated' people seem to think.
Saw Kanokon 5.
Kouta's never gonna get any. Though the way this anime does it, sexual situations is for comical purposes...
I'd HIGHLY recommend Please Teacher and e-f Tale of Memories for a mature adult look at a sexual relationship that can be taken seriously and not used only for fwap material...
Ultimately, I don't think Kouta and Chizuru will reach that 3rd base simply because Kouta just don't have the balls to take a relationship seriously as of yet.
Will he mature and grow for the task? That's what the end of this anime should hopefully answer.
Hoping that the protagonist evolves into someone better than the beginning of the series is usually what makes a good movie, TV series, anime, OAV, etc.
This anime has a chance. I say, give it that chance. Rosario + Vampire was dismissed as senseless but if the 2nd season [WOOT] follows the manga a bit closer, then we'll see some awesome...
