Boku to Kanojo no XXX, Gakuen Ouji

Also Nana to Kaoru?

They should fit 2, 3 and 5.

#4: Happy Tomorrow (SUENOBU Keiko) i think and Vitamin (SUENOBU Keiko), and i second Life too.

#6: maybe Kyou, Koi wo Hajimemasu

Genre search for #2:

Not a long list.

If you've ever thought or said "Nice Guys finish last" and really meant it, then you should probably read this LJ post by DivaLion. It's incredibly insightful whether you're male or female.

From a bumper sticker I like:
"If you're gonna ride my ass, at least pull my hair."

2.) Perhaps something like Love Monster

6. Honey x Honey Drops, Kyou, koi wo hajimemasu
   (most shoujo-smuts have teasing)

From the manga: Good Luck, Demon King!

2. Kedamono Damono
3. Ojiichan wa Shounen Tantei

The Kidnapping of Minja Jo's Boyfriend fits #1 I think.

It was all right - I read it a long time ago. Pretty art.
