Acting like you don't want to cum..

"No! Stop it! You're going to make me cum!"

Uhh.. why wouldn't you want that?

Really hate weird NTR stories. Like they'll sometimes ruin a story in the last fucking sentence of a doujinshi. It'll be like "but it was just a one night stand, and she went back to her abusive asshole boyfriend the very next day." Da fuck? Did they really need to include that? I hate it so much I will LITERALLY photoshop that crap out.

It's like some fucking doujinshi editor held a gun to the artists head or something. He's like "now insert that NTR shit I love so much." "Uh, sir, *gulp* the story is finished...there's not really any more room to-" "MAKE IT HAPPEN OR DIE!"

eventually i stopped noticing minor things like this
but they're still weird

There's a lot of things I don't like. Lots of the posts have already covered what I don't like... obnoxious girl noises and all the "AAHHH YES PLEASE CUM INSIDE ME!!!" parts are really annoying to me. But the thing that I'd say I hate the most is forced sex and rape. I can't stand to look at a cute girl who's crying while she's being forced to do something she doesn't want to do.

I really, really dislike futanaris, but in terms of tropes, I hate rape hentai when the girl decides that she's into it or that she secretly loves it or whatever. I want them to be hurt and broken and scared, and there's no fun in raping a willing victim (in hentai, of course, and hentai alone).

Furries.
Furry hentai is simply disgusting. I mean...Come on,it's an animal. It doesn't make any sense.

The SUPER UNREALISTIC girl gets raped by fat, bald,& repulsive guy & as times progresses she ends up liking it

Also the numerous times someone cums inside a woman & she'll never show signs of even remotely getting pregnant or fear of it,but it's also annoying because when they do worry about it like, "No,I'll get PREGNANT!!!!" you know nothing is going to happen to her & she won't get pregnant,I'm not into pregnancy like that, but it's just unrealistic

..I dont think you get how the reproductive system works..You can cum a million times into a woman and not make her pregnant..

Liquid breasts.
A real rack doesn't thrash and jiggle like an overly watered gelatin snack every time it's owner takes a step.

Biggest 'trope' is the lack of cohesive story in the 'the lil shit and his need for a revenge rape' category.

Sorry for the folks who enjoy these but I personally don't..

- furries: I know there's a ton on rule34 but I've never been a fan of animal sex. Guys with body hair and monster sex I'm totally okay with but something about furries just screams no. Maybe because lots of hair just makes me realize how uncomfortable it would feel to rub your sweaty body against it

- high-pitched female screams UUUGGHH. Yes, a lot of Japanese women sound like that because Japanese women are trained to an extra overly cute, submissive, feminine and high-pitched voice to cater to the average Japanese guy. I have tons of Japanese friends who sound like normal humans but put on this fake voice to either appear cute to their bf or for customer service. I'm Asian myself and I'm definitely not moaning like that

- that shy skinny teenager with the pretty boy face that you see in almost all hentai videos. UGGH. No. Please. Stop. I like looking at guys who have fat or muscle, who look slightly older, are perhaps taller than the female and don't look like they recently quit sucking on their mother's breasts

Hetero harem anime in general. Nothing bores the crap out of me like seeing a bunch of sexy girls (who are clearly down with "experimenting") fighting over some dimwitted male lead who's clearly never seen a vagina before. More lesbian orgy hentai, plz and thank you.

what about scalies (e.g. dragons) ?

Vore.
