What's a really specific ick that can make you drop a story??

Like something that's not in any way "bad" or "problematic" something that's a non-issue. For me it's sex scenes that feel sterile, idk how to explain it but some sex scenes lack intimacy and feel cold. im not that much of a fan of smut in the first place and i mostly skip them but i can appreciate a well built sex scenes with chemistry and sensuality to it, think sex scenes can be extremely good ways to show the connection between the love interests and good plot devices but honestly a good scenes of the leads just eye fucking each other with good chemistry, sensuality and intimacy is hotter than a lot of sex scenes lately
