The story

Christopher Ryan and Cacilda Jethá's bestseller makes a provocative argument: that human beings are not naturally monogamous, and that our prehistoric ancestors were far more sexually communal than modern assumptions allow. Lively and wide-ranging, it became a touchstone for conversations about non-monogamy and the mismatch between our instincts and our institutions. Sex at Dawn is a genuine bestseller and a provocative one — some researchers dispute its evolutionary claims, and we present it for readers to weigh themselves. Best for the intellectually curious who enjoy a bold thesis and want to make up their own minds about the science of human desire.

Questions before you buy?

Will this arrive in discreet packaging?
Yes — all orders ship in plain, unmarked boxes with no product names and no brand logos on the outside. We ship discreetly on every order, automatically.
What's your return policy?
Sex toys can't be returned once opened — that's an industry-standard hygiene rule, not specific to us. For defective or damaged items: we'll replace or refund. Email us and we'll handle it.
Is this product body-safe?
We carry only products that meet our editorial standard: body-safe materials, no phthalates, no BPA, no latex in products marketed for internal use. Our board sets the bar; this product meets it.
How do I clean it?
For non-motorized toys: warm water and mild soap, or a dedicated toy cleaner. For motorized or electronic toys: wipe with a damp cloth and toy cleaner — don't submerge unless the product is rated waterproof. Waterproof rating is noted in the specs section when applicable.
Is this rechargeable?
Check the specs section on this page for charging details. Most modern vibrators and massagers include a USB-C or magnetic charger. Battery-powered products are noted clearly in the Materials & specs accordion above.
Can I order anonymously?
Yes — guest checkout is available, no account required. We ship in plain packages with no external branding. The charge on your card statement appears as "Alexander Institute" — the parent company that owns Loving Sex, nothing that identifies the product type.
