oH gOOooOOD, I hate rape in yaoi's. If it's part of a backstory, or it's portrayed as something BAD, like it is, then yeah. But I hate it when it's non-consensual, but they're like "oh he's enjoying it so it's fine." Like if someone rapes someone and starts to catch feelings for them because he had sex with him? I really hate that, just pisses me o......
When the art style is really shitty, or when there's just TOO many things happening at once. If it's smut then I guess when the beta is childish. I don't dig incest either.
When the Uke is so fucking feminine that it be looking like a rare pokemon. Like what guy are you looking at to draw this character??? Huge ass eyes, skinny af, short af, etc. I like uniqueness in my yaoi. Ya feel? Some manly uke and shit makes things interesting. I also don't like that rape shit. Also, threesomes with twins just weird as fuck man.......
What stuff in yaoi turnes you off?
