I’ll divide my gripes between the gay and straight genres.
For straight porn, I hate what seems an obsession with the guy’s pleasure only. I hate to watch a scene where a thick, sexy woman has nice full titties with fat nipples a plump ass and a nice pussy. You’ll watch her suck the guys dick for 5 or so minutes and then he fucks her in the ass for 2 or 3 positions and cums. No kissing or pleasuring her. Never sucking or rubbing the titties or pussy. The worst offenders might not even take the bra off. I’m usually cursing at my phone like “Dude, are you afraid to touch the woman or what!?!?” What man fucking a woman doesn’t want to see her titties clapping back and forth??
Aside from that, I agree with what others have said. The fake orgasms and moans are the worst. And finally, for straight porn, these tiny-themed studios where they pair a guy that’s over 6’0 and a slightly larger cock with a girl that’s 4’11 and 95 pounds. When the girl first takes out the cock she spends 5 minutes gushing over it “Oh, it’s so big! I don’t think it’s going to fit in my pussy! It’s almost longer than my arm! OMG, I don’t think I can get it all the way in my mouth!!” Even when the guy is actually huge, it’s all so contrived and irritating.
For gay porn, I don’t really care for studios that treat the bottom like a ‘bitch’ or as if he is less than. I’m not talking about role-play or rough sex. I’m talking about a palpable disdain or even emasculation of the bottom by the top and/or directors of the film. Machofucker was insufferably horrible with this. Maybe I don’t understand it as I have never been fucked but I don’t think either of two men engaged in man sex is any less of a man than the other.
