^ No clue, but most manga on the reader are "for girls" in Japan.
Actually it's very much the opposite. Yuri manga are frequently labeled as shounen. Yuri Hime, for example, is considered a shounen publication. That's not to say girls don't read them or that all yuri is written for boys, but the target demographic for yuri focused publications is more often than not primarily male.
What that says about yuri as a genre I can't say, and as LGBTQ+ acceptance rises that might change, but as things are yuri manga are "intended" for boys (much like how most BL is, paradoxically, written by and for het women.)
I wouldn't be surprised if the western audience leaned more towards female than in Japan, but I don't have any information to base that on.
edit: We should do another dynasty demographic poll. Would be interesting to see if thats changed over the last few years, especially with covid having happened after the previous one was conducted.
