As someone who used to read erotica, I may be in the opposite side of this argument but I hate sex scenes in fiction. It’s amazing how many “great” writers absolutely suck at incorporating sex into their prose. Especially when it’s a really dark character who you know would be extremely into the act of sex, or a character who would likely be strongly affected by the act of sex, and the writer just phones it in. You can tell when a writer chickens out.
