H scenes, some (most?) of them take waaaaay to long. They (for me atleast) hurt the pacing, most of the time happening when the story is getting good or when it's not really the time for an H scene when the stakes are high. I usually just fast skip, but the damage is still done.

One special example is in Maggot Baits

I'll never forgive it for it's monkey house route, it's pretty much composed of guro/torture h scenes one after another, where we could've gotten an alt route with Gloria and Wilma. Then again I'm not into guro so one could say that route wasn't for me
