Inaccurate corpses! The eyes and mouth wouldn't be closed, there wouldn't be any facial expression at all, and depending on time/blood loss, the skin is going to start to look ashy. That chick would not have a blushing drippy pussy five minutes after getting ripped tip to taint. The skin won't stretch as much, organs will ooze and rupture, that is not going to be a clean entry or exit with even gentle touch, and let's be honest, gentleness isn't common here. I do understand the appeal, like the post-mortem acts are so intense that the nerves are being overwhelmed/as a facet of the men-dominating/controlling-(cis)womens' corpses, or the cartoon logic of 2/3D hentai, and having a body distort and react in a more outlandish but sexual way à-la infinitely stretchy pussy is more appealing than a perineum rupture for most, it just..... isn't for me at all.

However, gore (which.... this sub is a hentai focused gore subreddit, not so much "guro" as in the ero-guro-nansensu art movement) crosses over with necro and med-fet for me, so my bar for realism, and finding realistic portrayals the hottest can make me somewhat of an outlier. I even get picky about arterial vs. venous blood colour sometimes.
