Sextinction: The Decline of Sex and the Future of Intimacy

by Debra Soh

Dr. Debra Soh, neuroscientist, noted sex researcher, and author of the “exceptional” ( The Times , London) The End of Gender , reports on the hidden crisis of a sudden decline of sexual activity.

There’s a strange paradox in today’s developed society has never been more sexualized, but people across all age groups and demographics are having less sex than ever before. And nobody seems to know why or what to do about it.

The “fearless” (Eric R Weinstein, PhD, host of The Portal) Dr. Debra Soh leaves no stone unturned as she searches for science-backed answers. She takes us on a roller-coaster journey through ideological debates, new technological frontiers, and modern dating to understand the whys and hows of this issue.

With an expert and impartial eye, Soh examines these evolving and controversial developments and colors her findings with anecdotes from her personal research. Compulsively bingeable and groundbreaking, Sextinction upends the conventional wisdom surrounding sex, skewering pieties held by the right and left alike, and looks to the future of sexuality.

This book is basically the literary equivalent of someone looking around and saying, “Y’all need Jesus.” It’s bleak… really bleak. Debra Soh surveys just about every corner of the modern sexual landscape: the near-ubiquity of porn (and how extreme some of it has become), young women being cheered on for starting OnlyFans or becoming sugar babies, the rise of AI partners and sex robots, even the possible role of environmental factors like microplastics in declining libido. Nothing is off limits. I’ve been following the conversation for a while about people (single and married) having less sex, so I wasn’t new to the topic. Still, Soh introduced me to studies and data I hadn’t seen before. The research is thorough and wide-ranging, and she clearly knows the literature. That said, this is not light reading. It felt overwhelming at times. But honestly, I think parents of teens (especially boys), teachers, pastors, and anyone working with young adults should probably read it just to understand what’s going on. The ending is short but offers a bit of hope. For me, the book didn’t just leave me discouraged but it actually strengthened my resolve to step up as a husband and father and not just drift along with the culture. Bleak? Yes. But also clarifying.

Will someone think of those poor oppressed men: the book.
Women need to be more preoccupied with how not to be "threatening" to men, so men wouldn't feel "emasculated", than their own well-being. Apparently women aren't already performing enough emotional labor. Are you a successful career woman? Men will resent you, cheat on you, and prefer to marry a young, naive, unthreatening tradwife.

Gotta love seeing a woman who's an author, public speaker and "scientist" preaching for a world where women should best remember to stay 2 steps behind a man. Cutting a branch you sit on, or simply pulling up the ladder behind you?

Includes shaming of: autism, asexuality, polyamory, masturbation and contraceptives, among others.
