If you have read 6,000 books in your lifetime, or even 600, it’s probably because at some level you find “reality” a bit of a disappointment.
The only unnatural thing about sex is to not have any.
Women are socialized to make men feel good. We’re socialized to “let you down easy.” We’re not socialized to say a clear and direct “no.” We’re socialized to speak in hints and boost egos and let people save face. People who don’t respect the social contract (rapists, predators, assholes, pickup artists) are good at taking advantage of this. “No” is something we have to learn. “No” is something we have to earn. In fact, I’d argue that the ability to just say “no” to something, without further comment, apology, explanation, guilt, or thinking about it is one of the great rites of passage in growing up, and when you start saying it and saying it regularly the world often pushes back. And calls you names.
