old af thread at this point, but Princess Principal is a hella good show. It's free with Amazon Prime, check it out!

Mine's probably Neptune and Noir from Hyperdimension Neptunia. I love them so much and they make a real cute couple. <3

Your pairing doesn't have to be from an actual yuri work. :)

True, They're just the most reconizable and attention grabbing.

I think the vast majority of Yuri fans started with one or the other. Eventually you branch out and start finding stuff like Katanhe or LiliumXTriangle.

My absolute faviorite is, hands down, Girl Friends.

As far as things i haven't read yetand/or still in production, Lily Love is absolutely amazing, and i've seen more than a few comments about how the main couple are like an adult Ako and Mari.

Murcielao is another one I haven't quite finished yet, but just from what i've read so far, it's one of the funniest, yet goriest, things i've ever read. It's kinda like a more hardcore, and funnier, version of deadpool.(If you can believe it) And it's just great. Yuri isn't the main focus, but the main character does like girls. Maybe a little too much tbh...

I got into Yuri from Straberry Panic back in 2007. Almost immediately after that I found Girl friends. I credit both of those titles with my love of Yuri today. I've also played all of the Sono Hanabira games as well as some more obscure VNs such as Katahane.
