How is Maria†Holic shoujo-ai/yuri?
I've read the manga up through Volume 5, and I would describe it as a yuri comedy. None of the girl-girl relationships are developed in real depth, but Kanako is definitely a lesbian and is only attracted to Mariya insofar as he appears to be a girl. The two of them are not dating and Kanako has no interest in getting over her fear of men; in fact, Mariya's torture probably deepens her fear of men.

Kanako actually spends most of her time in the series chasing/lusting after various cute girls who are bona-fide females, such as her tomboy sempai Ryuken, the rotini-haired student council president, and Mariya's identical twin sister Shizu, who is a girl in disguise as a boy at an all-boys school (and hates men due to her experiences there). The comedy gets steadily weirder and takes over more and more as the series goes on, but Kanako being a lesbian is pretty much her defining trait and she never shows any sign of being attracted to men or of wanting to be.

If you're looking for a deep, romantic story, it's definitely not this, but there is real girl-girl attraction in Mariya-holic, so in that sense it can be called yuri.
