“Again they mention the Siriono who, they say, rarely if ever lack for sexual partners and where sex anxiety seems to be remarkably low. Recall that the Siriono live in small inbreeding groups under one roof and in a constant state of hunger, which makes food anxiety their main experience. Men use food to get sex, women are subservient, marriage is monogamous or polygynous, and women receive the blame for all adultery which is hidden as much as possible. A man alone with a woman in the forest may throw her to the ground and have sex with her without so much as a word. Sex is generally a violent and rapid affair, and while kissing is unknown, biting occurs.How would it feel to live in such a world, Ryan and Jethá ask. Hungry, probably, and not that great for women.”
