Watch yuri? I assure you you'll find better quality with all kinds of Erotic Anime when its manga style reading. There are a few good shows, but they're not usually Yuri specific. Since youre bisexual though I guess you could wade through some normal hentai to find yuri, because alot of good scenes are put into regular hentai, due to its emphasis on females.
Yuri/yaoi are the hardcore versions of boy love / girl love... Aoi Hana is shoujo-ai, but it's super sweet and can be a tearjerker. Just look for it online (subbed) =) I don't know any real yuri shows, however. I feel like there is a much larger section of yaoi than yuri, catering to a lot of straight girl fans. Just look at Junjou Romantica :/
This is gonna be tame stuff. You've probably already seen Strawberry Panic. If you want a love story I guess that's the way to go. I watched 5 or 6 episodes and got bored. I really enjoyed Ga-Rei Zero but it's actually about a strong friendship between two girls. It's got great fighting action. And depending on your morality, you could try Strike Witches. It's mostly fanservice. I swear they're all lesbians.
I haven't seen a lot of yuri, but here are some anime I've come across that might be of interest: Canon same-sex relationships/romantic feelings between women Revolutionary Girl Utena Sasameki Koto Blue Drop Bodacious Space Pirates Simoun Sailor Moon Strong subtext Puella Magi Madoka Magica El Cazador de la Bruja Noir Daybreak Illusion Honorable mentions (i.e. small amounts of "yuri" content, either canon or subtextual) Kino's Journey Jormungand Last Exile: Fam the Silver Wing Penguindrum Note that some of these are...not the most tasteful in their depictions, like Simoun and Penguindrum. I can provide more information if any sound interesting.
Try strawberry panic , sakura trick (sakura trick is new and the girls start off as a couple ) Kanazuki no miko , Mai Hime .
Maria-sama ga Miteru It's been a long time since I watched that. It's a good anime. I remember having a crush on Sei. :icon_bigg
