I skimmed Sex at Dawn way back when. Skim, because I saw so much of it as pretty self evident to me, especially in the context of having two long-term relationships with non-promiscuous but nonetheless: "cheating" women—in the context of "social norms." One lasted 7 years and encompassed three countries on two continents.
I pretty much dismissed all criticism of the book that lacked my level of perspective in that regard.
Caught this viddie this morning, a new interview with Christopher Ryan, co-author of the book with his hot wife, Cacilda Jethá. Just under 30 minutes and it'll give you the Cliff Notes.
I often think that the gulf between modern sexual "norms" (religion inspired, in order to keep female knickers firmly in place until a man backed by God's authority says they come down) vs. natural human desire is a way wider gulf than that between Paleo food and processed crap in a bag.
What do you think?
