One book in particular stands out when it comes to multi-partner relationships: "The Ethical Slut" by Dossie Easton and Catherine Liszt, now in its second edition.

The book "Polyamory: The New Love Without Limits" by Deborah Anapol also has plenty of value, particularly for long-term fidelitous networks. And the book "Sex at Dawn" by Christopher Ryan, PhD, and Cacilda Jethá, MB, re-examines the prehistoric origins of modern sexuality.
