What the Research on Body Count Actually Shows

The data every man should read before he commits.

Every man in my audience has thought about this at some point in his life. Some have asked about it directly on coaching calls. Some have argued about it in comment sections. Most have felt, at some level, that it matters - even when they couldn’t fully articulate why, and even when someone in their life told them they were being ridiculous for caring.

I have been saying it directly in my books for years.

“The higher the number of men she’s slept with, often results in her being far less likely to bond monogamously to a man, in a healthy way, over a long period of time.”

That is not an opinion. That is what the data shows. And the data has been accumulating for decades in peer-reviewed academic literature that almost nobody in mainstream culture wants to discuss.

This article is the discussion.

I covered the mechanics of this on the channel. The research below is what happens when the data catches up to what experience already showed.

The Baseline: Divorce Rates by Partner Count

The most comprehensive data on this comes from the work of Dr. Nicholas Wolfinger at the University of Utah, published through the Institute for Family Studies using three waves of the National Survey of Family Growth - data collected in 2002, 2006-2010, and 2011-2013. This is not a small sample or a fringe study. It is the largest and most methodologically rigorous dataset available on this question.

The five-year divorce rates in the 2000s, broken down by premarital partner count, look like this:

Women who married as virgins: roughly 6% divorced within five years.

Women with one prior partner: roughly 20%.

Women with two prior partners: roughly 30%.

Women with three to nine prior partners: roughly 25%.

Women with ten or more prior partners: roughly 33%.

I will address the apparent dip at three to nine partners in a moment, because skeptics always point to it and it is worth being honest about what it means. But the headline finding is clear: the lowest divorce rate is at zero or one prior partners, and it climbs substantially from there. A woman who was a virgin on her wedding day is roughly five times less likely to be divorced within five years than a woman who brought two prior partners into the marriage.

“If you want to get into a monogamous LTR, or take on the risk of marriage, then do it with a woman that’s a virgin or with a low notch count that lost her virginity later on in life.” - The Unplugged Alpha

The data says why.

The Relationship Stability Picture

Divorce rates capture the end point. But relationship quality before it gets to that point also matters, and the IFS published research in 2023 that looks at this more granularly.

Their finding: women who had only ever been with their husband - both having waited until marriage - had a 45% chance of reporting very high relationship stability. Women with five to nine lifetime sexual partners had a 25% chance. Women with ten or more lifetime partners had a 14% chance.

Not the divorce rate. The probability of having a highly stable, high-quality relationship in the first place.

45% for zero prior experience. 14% for ten or more.

The same research found that spouses who had only ever been with each other had the highest levels of sexual satisfaction and emotional connection of any group studied. Not because they were sexually inexperienced - because they had not previously allocated those bonds to other people.

This is the pair bonding mechanism I discuss in The Top Shelf Man. The neurological infrastructure for deep attachment - the oxytocin and dopamine systems that make exclusive pair bonding feel urgent and compelling - appears to function differently depending on how many prior activations it has experienced. The more prior partners, the more those systems seem to habituate. Not universally, and not deterministically. But consistently, across data sets, across decades, and across cultures.

The Premarital History and Divorce Connection

Teachman (2003), published in the Journal of Marriage and Family, found something specific that Wolfinger’s later work confirmed: the only women whose divorce rates were statistically comparable to virgins were women who had cohabited or had sex exclusively with their future husband before marriage - no one else.

Any other prior partner, regardless of the circumstances, significantly increased the probability of eventual marital dissolution. Not correlated slightly. Significantly.

This finding is important because it rules out the “it’s just about experience and comfort with intimacy” explanation. Women who were sexually experienced but exclusively with the man they married showed similar stability to virgins. The variable that drives the divorce risk is not having had sex before marriage - it is having had sex with other men before marriage.

The Infidelity Connection

Divorce is the terminal outcome. Infidelity is often what gets things there.

Wang’s analysis of General Social Survey data found that among divorced or separated women, 58% had cheated on a spouse. Among women who had never cheated, the divorce/separation rate was 17%. Among those who had cheated, it was over 40% - more than twice as high.

And separately, research published in a 2016 study on premarital relationships found that a history of premarital sexual relationships was significantly associated with both emotional infidelity and sexual infidelity within marriage. Prior sexual history and subsequent marital infidelity are statistically connected. They share underlying variance - which is exactly what you would expect from the pair bonding mechanism described above.

A woman who has formed and broken multiple pair bonds is not morally defective. She has, however, repeatedly practiced exactly the behavior that a successful marriage requires her not to engage in. And the data reflects that.

The Counterintuitive Finding (And Why It Does Not Change the Conclusion)

Here is the part that comes up every time this data gets discussed. The 2000s data shows a dip: women with three to nine prior partners had slightly lower divorce rates than women with two. This has been used to argue that the entire body of research is unreliable.

It does not support that conclusion.

Wolfinger himself addressed it directly in the study. The 33% five-year divorce rate for the 10+ group is not statistically significantly different from the 30% rate for the two-partner group - the sample sizes at the tails are smaller and the confidence intervals overlap. What is statistically robust is the cluster at the bottom: zero and one prior partners, consistently lowest, consistently separated from everything above by a large and significant margin.

The practical conclusion does not change. Zero to one prior partners - best outcomes. Two or more - substantially worse. The difference between 25% and 33% in the middle range is noise. The difference between 6% and 30% at the extremes is signal.

What She’ll Tell You (And What to Do About It)

I want to address the practical reality, because the research matters but the coaching matters more.

“Women will never reveal the truth about their notch count to you, so don’t bother asking to get an authentic number.”

I wrote that in The Unplugged Alpha and I stand behind every word of it. The number she gives you is not the number. There are social desirability pressures that cause women to underreport systematically, there is genuine memory variance in how women categorize certain experiences as “partners” or not, and there is the simple reality that she knows what you want to hear.

“At a bare minimum, double whatever number she gives you.”

The research does not give you a magic number cutoff where you should walk away and a magic number below which everything will be fine. What it gives you is a framework for understanding risk, and a reason to take the behavioral signals seriously that she is giving you during the vetting process.

How does she talk about her exes? Does she have a string of serious relationships, or a string of experiences that never went anywhere? When did she lose her virginity, and under what circumstances? What does her relationship history actually look like when you piece it together over time - because women who have had a lot of partners leave traces of it in their stories, even when the number itself never gets said out loud.

The research tells you what the data shows. Vetting tells you where she actually sits on the distribution.

“Gee, I wish my wife had slept with 50 more guys before I married her.” Said no man ever. - The Top Shelf Man

What This Is Not

I want to be precise about what I am and am not saying, because this topic generates a specific kind of bad-faith response.

This is not a moral argument. I am not telling you that women with high partner counts are bad people who deserve to be alone. The research does not make that claim and neither do I.

This is a risk management argument. The data shows that certain characteristics correlate with worse relationship outcomes, and that body count is one of those characteristics. Just as I use the 21 Red Flags as a vetting framework - not to punish women for their past but to make better decisions about what I am exposing myself to - the body count data is a calibration tool for men who are seriously considering long-term commitment.

The man who ignores this data because it makes him uncomfortable is the same man who ignores the other red flags because he is too invested to see clearly. That man ends up in a statistic. He ends up paying the price that the research predicted.

You have the data. Use it.

In Conclusion

This is not a new conversation. Men have known intuitively for generations that a woman’s history mattered. The research has now confirmed, repeatedly, across multiple datasets, across multiple methodologies, across multiple decades, that the intuition was correct.

Women who come to marriage with zero or one prior sexual partner have dramatically better outcomes on every measure that matters - divorce rates, relationship stability, sexual satisfaction, emotional connection, and fidelity. Women with ten or more prior partners have the worst outcomes on every measure. The gradient between those two poles is real, consistent, and statistically significant.

That is the research. The rest is what you decide to do with it.

The Cold, Hard Truth

Never forget:

• Women who married as virgins had roughly a 6% divorce rate within five years, according to Wolfinger’s IFS research using National Survey of Family Growth data. Women with two prior partners had roughly a 30% rate. Women with ten or more had roughly a 33% rate. The lowest risk is at zero or one, and it rises substantially from there.

• IFS research published in 2023 found that couples where both partners had only ever been with each other had a 45% chance of very high relationship stability. Couples where one or both partners had ten or more prior partners had a 14% chance. That is the real number behind the data.

• Teachman (2003) found that the only women whose divorce rates were statistically comparable to virgins were women who had been sexually active only with their future husband before marriage. Any other prior partner significantly increased divorce risk.

• Women will underreport their partner count. At a bare minimum, double whatever number she gives you. The number she provides is a starting point for your assessment, not the answer.

• This is not a moral argument. It is a risk management framework. The data tells you where the risk distribution actually sits. What you do with that information is your decision.

• “If you want to get into a monogamous LTR, or take on the risk of marriage, then do it with a woman that’s a virgin or with a low notch count that lost her virginity later on in life.” The research supports that recommendation completely.

Peace.
