Good ecchi anime?
Looking for suggestions. Let's break it:

- When I say good, I don't really care if it's a masterpiece or one of the worst things ever written. I just want noods; as often as possible.
-I'm not looking for anything even close to hentai, just softcore. Nipples is as far as it goes (actually if it has some, it would be nice).
-I don't want to see anything that I've seen before already.

Things I've already seen:
-Seikon no Qwaser.
-Green Green.
-Ikkitousen (all seasons).
-Rosario Vampire.
-Love Hina.
-Elfen lied (Not ecchi, but tons of nudes).
-Bastard.
-Cutey Honey.
-Girls Bravo.
-Kanokon.

Among other that I don't remember right now. I'm not a very knowledeable person about this, so I actually need help to find an anime.
