Hentai Anime

Seems that quite a few of you are into watching "hentai" or ero anime.
Seen the quality of some and most of them are pretty poor so I don't really look out for them.

Actually I don't have a favorite, honestly I've only watched 3 hentai series; Bible Black, Night Shift Nurses and Tournament of the the Gods, and all of them sucked specially Bible Black I felt ill while watching it but I admit it the characters are beautiful.

So I wonder if you guys have a favorite hentai series? not only dudes I will be gladly surprised to hear girl's opinion in this one.

I might get some ideas ^_^ just so my list grows ^^;
