Getenrou is great, and I’d honestly recommend all of Ishiguro Masakazu’s other works, as well. I’m especially fond of Soremachi and his one-shot, Karakuri.
But yeah, I thought I’d make a few yuri recommendations of my own:
Omoi no Kakera/Fragments of Love (by Takemiya Jin):
A lesbian drama series following a protagonist whose experiences have made her uninterested in love. Notable for having characters with explicit LGBT identities who actually talk about what it’s like with each-other.
for rape in the side-story.
Watashi no Sekai o Kousei Suru Chiri no You na Nanika/These Feelings We All Must Endure (by Amano Shuninta):
A much darker adult lesbian drama following a group of seven women and their intertwining, sometimes harmful relationships between each-other. Has the only asexual lesbian character I’ve ever seen in a work of fiction.
for abuse and eating disorders. Also 
.
Collectors (by Nishi Uko):
A cute 4koma about a woman who collects books, a woman who collections clothes, and their relationship together.
Honey & Honey (by Takeuchi Sachiko)
An autobiographical comedy series about lesbian life in Japan. It goes into a lot of details about LGBT culture in Japan that don’t really come up in yuri series, so it’s a pretty fascinating read.
