What's your H pet peeve?

Anatomy fails. Vaginas in the wrong place, dicks so big they'd cause unconsciousness from decreased blood to the brain, impossible body contortions...

Also, urination.

Wimpy male protagonists. I hate them.

Those rape doujins where the girl becomes a sex-addict the moment she gets penetrated.

I'm turned off by hentai that escalates within the shortest timeframe imaginable - no foreplay, no dialogue, no back story, no character development whatsoever. Instead of a brisk transition and some tone-setting, you just click or turn to page one and you've got globs of semen spewing all over the place and a girl drooling like a two-year-old on crystal meth. I also find it distasteful if there's no kindling of any kind of romantic flame, or the characters haven't at least some semblance of being emotionally intertwined. And also.. I know this is going to put me at the margins of this community, but I don't like it if there's no boys. Don't ask why. x3
