Nagisa Furuya is top tier though her series are shounen ai
If you like stories that are slightly darker, Harada and Scarlet Beriko

For a consistent yaoi author
Itsuki Makoto (stories are a little freakier though)
Kashima Chiaki (it feels like they have more affection?)
Nago Nayuta (i like the softness of a lot of their works)
Yoneda Kou (stories are more about grown men so its an interesting tone)
Ichikawa Kei (The ukes are normally a bit feistier which i find cute)
Kurahashi Tomo (warm? like physically?)
Suzumaru Minta ( art style is super cute and the ukes are normally super cute as people)
Yoshio Akira (the semes in the story are normally very affectionate and loving)
