Basiclly, anything that is over or exactly 10 volumes. One could say it's two-digits fetish of mine 🤣

And yes, there is many good, short manga's (i.e. "Utopia of Homosexuality" or "Complex"), I am aware of this.It's just I have appetite for something longer, bigger, with more plot...

I have read;

Let Dai
Love Mode
Loveless

...
oh, I'm really suprised those are only 10+ series I know. Ashmed of myself, really :blush:

1001 Nights is the only one I'm bring to mind right now.

Kiss Me Princess is 9 volumes.

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."

Junjou Romantica
Double Call
Silver Diamond
Eroica Yori Ai wo Komete
Kiss Me Princess ~~ well it is only 9 volumes but it is really really good^^
Bronze and its prequels...
Koori no Mamono no Monogatari

Yami no Matsuei
Kaze to Ki no Uta
Count Cain + Godchild - together more than 10 volumes but they are not really shounen-ai.

I haven't read these but here are some series for you...

Kaze to Ki no Uta this has 17 regular volumes and 10 bunkobon
Kusatta Kyoushi no Houteishiki 10 volumes exactly
Komatta Toki ni wa Hoshi ni Kike!
Banana Fish

and this thread might help you...
Yaoi with long story or shounen-ai

And Animal X might work too.

Junjou Romantica (it is that long? Didn't realize that. Cauze it's rather boring)
Bronze (cant' stand art)
Zetsuai (@up)
Kaze to Ki no Uta (very good, anime based on it is one of few I can stand. Btw - isn't that first manga where malexmale sex was important part of plot?)

Forgot to mention those when I was making a list of what I have already 'did' ( ; - ) ). I'm really, really sorry.

I have read Komatta Toki ni wa Hoshi ni Kike! yesteday (today was released v11c01 by Bliss, btw).

For other titles, I'm very, very very very very very grateful 😀 Thanks ;D May yaoi god bless you ; )

edit:
ps: I also checked some mangas from that thread you mentioned, Toto, and they seems 'edible' ; - )

Going to eat now. Yes, I am the Eat-man : P

So these are all shounen-ai.... sorry about that.

There's always G-Defend, which is - count them - a whopping 35 volumes long and still going strong. By the same mangaka, there's also Jinjuu Houretsuden, which clocks in at 13 volumes long and is possibly the lightest shounen-ai you will ever see. No, really, it's barely even shounen-ai, but it's so sweet, I love it. There's also Yami no Kodou, which is some 18 volumes long and ongoing. Another one is Ryuu no Yuigon, which is 12 volumes long. And someone already mentioned them, but I also strongly recommend Koori no Mamono no Monogatari and Silver Diamond by Sugiura Shiho, they're amazing.

...And if you don't know Japanese, I apologize. Only Koori has scanlations past your ten-volume mark. Uh, keep them noted for future reading?

Gravitation

Kamui
Mainichi Seiten <3
Kusatta Kyoushi no Houteishiki
Teikoku Kyoudai

Yatteraneeze! is one very nice one but there's only 7 volumes.

Zankoku na Kami ga Shihaisuru almost cpl. scanlated, only 1 ch. left
ZE
Koisuru Boukun already 8 vol. out, plus there are enough chappies out for a 9th tanko ...

Maybe it is useful:

These would be great suggestions if they were all completed series. A lot of these are on hiatus or have been dropped by the scanlators.
