Casual Sex Meaning
A story setup where two characters agree to a purely physical arrangement with no romantic expectations, only for feelings, jealousy, or emotional intimacy to complicate the deal. In romance and erotica, it functions as a promise the characters make to themselves that the plot will inevitably break.
Why readers love it
Readers love the tension between what the characters claim they want and what they actually need, and the slow collapse of their own rules is the entire payoff. The arrangement also lets the physical relationship start early while the emotional one has somewhere to go, so the story runs on anticipation rather than withholding.
