I’ve been sick and not able to comment on these before now, but @Goyavoyage has a really solid list of recommended yuri titles and is doing a great job of highlighting them.
How Do We Relationship? in particular I would easily put in the top three of yuri titles currently being serialized. And here’s something @Goyavoyage didn’t mention: if you live in the US or Canada and can afford $1.99 a month (in the US) for a Viz Manga subscription (not to be confused with a Shonen Jump subscription) then you can read new chapters of HDWR as soon as they’re published in Japan (currently up to chapter 114). (The Viz Manga site is missing chapters 84-93, corresponding to volume 10, so you’d have to buy that separately.)
