Manga, is basically a Japanese comic book but most of the scans here are translated into English. You have yaoi manga that are gay comics drawn by a fujoshi (women who love gays), and then you also have bara which are gay comics drawn by lads. The major difference between yaoi and bara is the art style, since in yaoi the men seem to be quite lean, clean-cut, and all that shit that you usually see in anime, while in Bara men tend to be quite butch. You will know just what I mean when you read some of the presented stories. If you do not know all of the anime terms, you might have a difficult time understanding some of their tags as well. I would just like to say that not all yaoi and bara manga is meant to make you hard, some of them are love stories written by loners (or so I assume), while some of those manga are actually quite fucking arousing. This all depends on the shit you want to read yourself because on you have a lot of different comics, so make sure to properly explore. I really appreciate their dark design, and the user-friendly layout, as this makes everything so much easier for me.
I was able to find whatever the fuck I was searching for with ease.
Now, while they do not have a special section for the categories, which I find utterly fucking annoying, they do have some tags listed when you open any of the manga.
