Things about yaoi that turns you off/ you dislike?

For me when in the story the uke unrealistically acts as a girl, and ESPECIALLY when the seme's dick is too damn big for a lil petite uke... I mean seriously that's an ass he boutta fuck, like I don't enjoy that because the uke will only feel pain and i'm sure it won't really be pleasurable--- share your turn off or dislikes lmao
