What if the biggest obstacle to better sex is... thinking about sex?
I was on a red-eye back from a client site in Austin, couldn't sleep, and figured hey, let's listen to something my seatmate absolutely cannot see on my screen. So I queued up Marty Klein's Sexual Intelligence at 1.75x (more on that in a second) and settled in for what I expected to be another self-help book that takes one decent insight and stretches it across eight hours like taffy.
I was half right.
The Consulting Framework Your Bedroom Actually Needs
Klein's central thesis is deceptively simple: most people approach sex with the wrong KPIs. We're measuring performance, appearance, frequency, and "normalcy" when we should be optimizing for presence, curiosity, and communication. If that sounds obvious, consider how many couples Klein has counseled over 30 years who intellectually know this but still spend intimate moments running an internal audit of their body fat percentage.
Here's where it gets interesting. Klein breaks sexual intelligence into three components - information, self-knowledge, and acceptance of the human body as it actually is (not as Instagram suggests it should be). And he's ruthless about calling out the cultural machinery that keeps us anxious. He goes after the pharmaceutical industry's vested interest in medicalizing normal sexual variation. He dismantles the myth that spontaneous desire is the only "real" desire. He points out that most sex education teaches plumbing, not intimacy.
This is what my parents did instinctively - not the sex part, obviously, but the principle of ignoring what you're "supposed" to want and focusing on what actually works. My mom and dad didn't need a relationship book to know that showing up consistently matters more than grand gestures. Klein is basically saying the same thing, but for the bedroom. The relational consistency angle reminded me of what Harville Hendrix works through in Getting the Love You Want — different entry point, same underlying argument that most couples are solving for the wrong problem.
Where the Padding Lives (And It's Not Where You'd Expect)
At 7 hours and 36 minutes, this is actually pretty lean for a self-help book. But Klein still falls into the classic trap of repeating his core framework through different case studies that start blurring together by hour five. Couple A worries about erectile function. Couple B worries about desire mismatch. Couple C worries about being "normal." Klein walks each through the same reframe: stop judging, start communicating, accept your body. The insight is valuable. Hearing it applied the seventh time? Less so.
The key takeaway is worth the listen. The other 7 hours? Maybe 5 of them are.
What I genuinely appreciated - and this is rare for books in this space - is that Klein doesn't traffic in toxic positivity. He doesn't promise mind-blowing sex if you just "let go." He's honest that some sexual problems are medical, some are relational, and some are just... life. Aging bodies, stress, kids banging on the door. He treats his readers like adults, which is (ironically) unusual for books about adult topics.
Alan Winter Sounds Like Your Therapist's Therapist
Alan Winter narrates this like a clinician who's seen everything and judges nothing. There's a calm, measured quality to his delivery that works perfectly for material that could easily tip into either clinical sterility or late-night-infomercial sleaziness. He threads that needle. You never feel like you're being lectured, and you never feel like you're listening to a self-help guru trying to sell you a weekend retreat.
He also handles Klein's occasional dry humor well - there's a passage about how couples describe their sex lives using the exact same euphemisms they'd use to describe a restaurant meal ("it was fine," "nothing special," "we used to go more often") and Winter delivers it with just enough wry understatement that it lands.
I bumped back down to 1.5x for some of the denser sections on sexual response cycles. At 2.0x, the clinical terminology starts piling up faster than you can process. Not a knock on Winter - the content just demands a bit more attention than your average business book.
Who Gets ROI Here
Anyone in a long-term relationship who's noticed the conversation about sex has gotten... smaller. Couples where the intimacy hasn't disappeared but has gotten routine, predictable, slightly anxious. Also genuinely useful for anyone who grew up in a conservative household (Korean church kid here, raising my hand) where sex education was basically "don't." Klein fills in the gaps that abstinence-only messaging created.
Skip this if you're looking for technique guides or position recommendations. That's not what this is. This is the strategy deck, not the execution playbook.
The Engagement Letter
Bottom line: Klein wrote a smart, no-nonsense book about why we're bad at sex and what to do about it. It's 30% too long, but the core 70% is genuinely useful. I've seen the anxiety he describes - the performance monitoring, the normalcy obsession - play out in how executives approach everything from boardrooms to bedrooms. Turns out the fix is the same: stop measuring the wrong things.
Jenny would say I'm being harsh about the repetition. Jenny is right. But she'd also agree this was worth the listen.
(She doesn't know I listened to it on a plane. We're keeping it that way.)
