"In this groundbreaking book, Dr Regnerus draws on several large, population based surveys to provide a representative overview of what Americans think and do with regard to sexual relationships, supplemented by stories from in-depth interviews with100 young adults aged 24-32 conducted by his research team." -- The Family Education Trust Bulletin Issue 170

"This book has the same message as George Gilder's Men and Marriage which came out a couple of decades back... Is this book unduly pessimistic? No, it is quite realistic...and a much needed wake-up call." -- Dr Pravin Thevathasan, Catholic Medical Quarterly

"A magisterial study of the changing sexual landscape today, which gives special attention to the impact of the digital revolution on sexual behaviour and relationships. Will become a standard work of reference in the field." -- Anthony Giddens, author of The Transformation of Intimacy: Sexuality, Love, and Eroticism in Modern Societies

"Mark Regnerus has been a pioneer in the study of how sexuality is changing in modern society. This book is an utterly fascinating, sometimes disturbing, occasionally provocative, brilliantly thoughtful, and always informative account of what he has learned about sex in America in the 21st century. It offers a wealth of insights about changes in how love relates to sex and friendship, in how people form and change their sexual self-concepts, and in the directions of sexual trends. This is an indispensable read for anyone wishing to understand the sex lives of today's adults, as well as how the rapid changes in sexuality reverberate through the complex negotiation of romantic relationships." -- Roy F. Baumeister, co-author of Willpower: Rediscovering the Greatest Human Strength

"Mark Regnerus shows us that when sexual access is plentiful and requires little effort, then sex is cheap--easy to get and not a big deal. The shift from expensive sex to cheap sex was ignited by the pill, fueled by the internet and dating sites and the ready availability of high-quality pornography. The consequences of cheap sex are profound and complex, and not all positive. Regnerus has a breezy, likable way of telling this fascinating and engaging story. A great read." -- Linda Waite, Lucy Flower Professor in Urban Sociology, University of Chicago

"Too many young men in America are checked out from work, family, and community. Why are so many of our young men floundering? In this provocative new book, Cheap Sex, Mark Regnerus argues that the availability of low-cost sex and the decline of marriage have made it harder for young men to embrace adult responsibilities. Everyone concerned about the plight of young men in America should wrestle with the arguments in this important book." -- W. Bradford Wilcox, Director, National Marriage Project, University of Virginia
