Why 40% of Wives Admitted They’ve Lost Interest in Sex
And Why the Real Number Is Far Worse
A national survey of over 11,500 people, published in BMJ Open - one of the most respected medical journals in the world - found that 40% of women in relationships longer than five years reported losing interest in sex for three months or more in the past year. Forty percent.
Men in those same relationships? Near-flat, averaging 15% (range: 13-16.1% across all durations).
But here’s what should really concern you. That 40% is only the women who admitted it on a clinical survey - and only the ones who’d gone cold for three straight months. That’s a high bar. A woman who’s going through the motions once a month, never initiating, treating sex like a chore she tolerates - she doesn’t show up in that number. The 40% is the floor, not the ceiling.
And the rest of the data backs that up. According to the General Social Survey - the longest-running study of American social behavior - only 49% of married couples are having sex once a week or more. Down from 59% just a decade ago. And a 2002 study out of Germany found that as relationships get longer, sexual desire declines in women - and only in women. Men’s desire stays the same. Hers goes one direction. Down.
This isn’t a 40% problem. This is the default.
The Study That Proves It
In 2019, researchers at Florida State University published a longitudinal study that tracked 207 newlywed couples over the first four to five years of their marriages. They checked in every six months. Measured desire. Measured satisfaction. Tracked it all.
Here’s what they found.
The average wife’s sexual desire declined steadily from the day she walked down the aisle. Not 40% of wives - the average. The mean trajectory for all wives in the study pointed down. Meanwhile, the husband’s desire showed no change at all. His desire at year five was the same as the day he said “I do.”
But here’s the part that should make every man reading this sit up straight.
Declines in her desire - not his - predicted declines in both partners’ marital satisfaction. Read that again. When she loses desire for you, the entire marriage suffers. Both of you become unhappier. And the researchers found that the husband’s level of sexual desire was “irrelevant to anybody’s marital happiness.”
Her desire is the engine. When it dies, the marriage dies. Not his. Hers.
Why I’ve Been Saying This for Years
If you’ve read The Top Shelf Man, or my first book, none of this should surprise you. I’ve been talking about Genuine Burning Desire (i.e. GBD) for years now. Not because I pulled it out of thin air, but because I’ve had well over a thousand coaching calls with men living this exact pattern.
They call me and they say the same thing: “Rich, everything is fine on paper. We don’t fight. She’s a good mother. But she doesn’t want me anymore. She flinches when I touch her. Sex feels like a chore she’s checking off a list - when it happens at all.”
And I always ask them the same question: “When did it start?”
The answer is always some version of “a few years in.” A few years. Right on schedule with what these studies confirmed.
Sex is the glue holding relationships together. If she isn’t craving you - your body, your touch, that raw intimacy - there’s zero point in a long-term setup with her. I wrote that in The Top Shelf Man, and every piece of research I’ve seen since has backed it up.
The 40% who admitted it on a survey aren’t broken. They’re just the ones who’ve already arrived at the destination. The rest are on the highway headed to the same place. And the reason is predictable - because the men in those relationships made the same mistakes that I’ve been warning you about.
The Three Killers
In The Top Shelf Man, I dedicated an entire chapter to what I call the Three Ity’s - the three killers of long-term desire. Proximity, Familiarity, and Exclusivity. Society pushes women to demand all three, and men cave - because we naturally want the women we love to be happy. But just because a woman wants something doesn’t mean you should give it to her. Sometimes the very things she’s asking you to change are actually bad for her long-term attraction.
Proximity. You move in together too fast. You’re around each other all the time. You save on rent, you cut your commute to see her, and you think you’re building something. What you’re actually doing is removing the space that desire needs to breathe. I’ve seen very few relationships that lasted decades where the man didn’t have significant time apart from his woman. Every single one of them credits some version of “distance” as the key.
Familiarity. Familiarity breeds contempt - that’s an old saying for a reason. When you first meet, she sees your confidence and competence. But as she spends more time around you, your insecurities reveal themselves, your routine becomes predictable, and the mystery that attracted her in the first place dies. You’ve got to remain somewhat of a mystery to her. Don’t become too predictable, or too available. Women will push for more of your time - that’s to placate their own needs or anxieties. But giving her everything she asks for is often the very thing that kills her attraction.
Exclusivity. This one is the hardest for men to accept. But here’s what the research shows and what I’ve observed across thousands of coaching calls: a woman needs to know, on some level, that other women find you attractive. That you have options. Not because you’re going to act on them - but because the knowledge that you could is what keeps desire alive. Social proof is the subtle dread that keeps her on her toes. Close that door entirely, and you’ll watch her GBD for you drop faster than you thought possible.
The men whose women lost desire gave away all three. Too close. Too familiar. Too locked down. And once that happened, desire didn’t just dip - it died.
If you want to hear me break this down in detail - with real coaching examples - watch this.
What the Rare Exceptions Do Differently
Look, I’m not going to sugarcoat this. As men, we need to expect our return on investment in the relationship to dip over time. A decade in and you might be with a woman who started at a solid 10/10 GBD early on, but now sits at an 8/10 - even as you’ve continued to stack more wealth and success. Your value goes up, but you will experience less GBD in return. That’s reality.
But there’s a massive difference between an 8/10 and a zero. And the men whose women still genuinely want them after five, ten, fifteen years - they aren’t lucky. They aren’t the majority. They’re rare. And they’re doing the work that most men refuse to do.
You maintain space. You don’t live in her pocket. You have your own schedule, your own mission, your own life that she gets to be a part of - not the other way around. If her GBD is truly high, she’ll gladly mold her schedule around yours.
You stay unpredictable. You mix things up. You don’t become the guy who does the same thing every weekend, eats at the same restaurant, and watches the same shows on the couch every night. You can do anything to a woman - except bore her.
You keep stacking value. Your looks will decrease over time - that’s biology. But your wealth, your status, your competence, your network, your physical fitness - those are all in your control. The key to retention and GBD with women will always remain men maximizing their attractiveness, and value.
And you vet properly from the start. One of the green flags I laid out in The Top Shelf Man: she genuinely craves sexual intimacy with you. Not tolerates it. Not offers it as a reward. Craves it. If that’s not there in the beginning, no amount of managing the Three Ity’s will manufacture it later. GBD cannot be manufactured.
The Cold, Hard Truth
The science is in. The average wife’s desire declines from the wedding day forward. Over half of married couples aren’t even having sex once a week. One in five marriages is fully sexless. And 40% of women in long-term relationships will flat out tell a researcher they’ve lost interest - which means the real number of women running on empty is far higher.
This is the default. This is what happens when men don’t know what they’re doing. When they get comfortable. When they give away proximity, familiarity, and exclusivity because society told them that’s what a good partner does - and then they wonder why she’s “not in the mood” for the third month in a row.
Her desire is the engine of the relationship. When it dies, everything dies. And it doesn’t die randomly - it dies because the conditions that created it were slowly, methodically dismantled by men who didn’t know any better.
Now you know better.
If you want to understand why she lost desire in the first place, I laid the foundation in The Unplugged Alpha. And if you want to know how to build a relationship where she doesn’t - how to vet, how to lead, how to manage the Three Ity’s and maintain GBD for the long haul - that’s The Top Shelf Man.
Most men will read this and do nothing. That’s why they’re in the majority.
Don’t be most men.
Peace.
