I guess that's all I can remember and most of 'em are manga since I am totally addicted to manga for now .. :) But it also depends what kind of genre your girlfriend likes .. Coz there are some instances where girls become yaoi/shonen-ai fans .. :) Like me ..

Here are some shounen-ai just incase:

Junjou Romantica - Best of the best! ( A little yaoi )
Sukisyo! ( A little yaoi )
Loveless ( ? )
Kyou kara Maou ( JUST Shounen-ai )

That's all I could think of ..
