This one is really good!

This is the only yuri I ever read and found it truly exceptional.
It's hard to find yuri with a good median between sex incorporated into the plot and full out smut. Here's some I'd recommend
Indigo Blue- It's slice of life but has some sex scenes, however the sex isn't very explicit. It's not full of fluff either

Mars no Kiss- There's no yuri sex scenes in the manga but there's a bit of sexual tension between the two main characters. If you can't stand heterosexual sex don't read it though (the sex isn't smutty)

Magan&Danai- this one is actually very fluffy and sweet but I love it lol. Unfortunately there's only 18 chapters and they're all short

Gunjou and Pulse are good too.
i'd like to read some yuri but can't find anything that suit my taste. the things i dislike very much are too much ecchi (like there's an unnecessary amount of fanservice out there for everything), boring plot (and i say this bc every yuri manga i read these days is really boring idk i like slice of life but where's the fun part idk it's almost like every yuri is too fluffy, or too sexually appealing or too plain wtf help) ( ̄ε(# ̄)Σ
