Idk i just click on a random story, scroll down to its tags and click on one to open the seach section
If you look at the very top bar, you have Yaoi, Yuri, etc, then All Genre. You can click on any of them and it will lead you to the works in that catergory as well as tags you can click on to include or exclude to filter with.
Just add everything to yaoi I m doing this since 2016 lol
That’s how you search by genre, not by tag.
I genuinely have no idea how to get to the “tag search” part of this website without manually adding ‘/tag/’ to the end of the search bar, but if anyone knows (on PC) please do let me know, lol
And for those of you who didn’t even know this was a thing, here;
