Hmm.. that is a mystery..
I would have thought the market was bigger for girl/girl manga stories, but then again I'm not as familiar with it as you.
Any good titles you'd recommend me to start with? There is a comic shop in Vienna where I could look.
For shonen-ai and yaoi titles I recommend the following titles (I've put the publishers in brackets for you:
Eerie Queerie by Shuri Shiozu [pub: Tokyopop]
Our Kingdom by Naduki Koujima [pub: DMP/Juné]
Demon Diary by Kara Lim [pub: Tokyopop]
Freefall Romance by Hyouta Fujiyama [pub: DMP/Juné]
Black Knight by Kai Tsurugi [pub: Blu]
Only the Ring Finger Knows by Satoru Kannagi [pub: DMP/Juné] [is a one volume manga and is also available in novel form with several sequels].
Truly Kindly by Fumi Yoshinaga [pub: Blu] [A collection of short stories including the first appearance of French aristocrat and butler characters Antoine and Claude]
Lovers in the Night by Fumi Yoshinaga [pub: Blu] [A full one-shot manga revolving around Claude and Antoine]
Fumi Yushinaga has also done some other series I'm interested in reading including Antique Bakery and Gerard and Jacques.
Finally there's the DMP/Juné yaoi collection by Biblos which is a big collection of short stories by various yaoi/shonen-ai manga-kas (including Naduki Koujima!) and it is called J-Boy.
NB: DMP (Digital Manga Publishing) is the name that used to appear on their yaoi titles until 2006. Now they're all published with Juné on their covers. Also their manga is slightly more expensive than other publishers because they're slightly bigger and come with dust jackets.
A shojo-ai title I'd love to read is Blue by Kiriko Nananan but I can't find it at an affordable price.
On the bright side I have been able to find Strawberry Panic by Sakurako Kimino which I can't wait to read as it looks really adorable. ^_^
Assuming direct control...
