The Science Of How Men Fall In Love

Dating expert Adam LoDolce helps unravel the mysteries of men and love.

I don’t remember the first time my boyfriend told me he loved me. But I do remember one particular afternoon, when we’d been dating about six months. He’d been saying those three little words on the regular for quite a while already, but on that day, he pulled me close, kissed me, and whispered, “I think I’m really falling in love with you.”

I burst out laughing. “What do you mean, you think you’re falling in love with me?” I said with mock incredulity. “I already know you love me. And I love you, too.”

He looked sheepish and clumsily attempted to explain. Maybe, he said, he was falling in love with me on another, deeper level. I kissed him so he’d stop talking.

I still tease him about it – but part of me has always been a little wary, too. What did he mean, he was falling in love on another level? On what level did he love me before?

Turns out, science might have the answer. For one thing, contrary to popular belief, it seems that men actually fall in love faster than women do. That cliché of a woman falling head-over-heels on the first date, becoming obsessed, and desperately chasing a noncommittal man? It’s not only sexist, it’s wrong.

I asked dating expert Adam LoDolce, founder of Sexy Confidence – a website dedicated to helping women attract the right kind of guy and have the kind of love life they really want – to shed some light on the topic of men and love. What exactly is it that makes a man fall in love?

Fools rush in

A 2010 study of 172 college students, published in the Journal of Social Psychology, found that men not only fall in love faster, they say “I love you” sooner than women do. Psychologist Marissa Harrison, who co-authored the study, said participants were surprised by the results.

“Both men and women in our study presumed that women would fall in love and say ‘I love you’ faster than men. Women are assumed to be emotional; sometimes overly so, or rash,” she told Broadly.

But psychologist Neil Lamont didn’t find the results surprising at all. “Meaningful relating is as important to men as it is to women. And while societal and cultural norms may have dictated that men should be strong and resilient, the reality is [that] a well-lived life for men will typically involve deep and meaningful, loving relationships.”

What have you got to lose?

When men fall in love (and women too, for that matter) their brains are flooded with “feelgood” chemicals: namely, dopamine, norepinephrine, phenylethylamine, oxytocin, and for men, testosterone. So a man who gets moony over you right off that bat is under the influence of strong hormones, which are kicked off by your pheromones – the chemicals we give off in order to attract mates.

There’s good reason for men to fall in love faster, and thus fall under the spell of these chemicals: it’s evolution. Harrison explains why women might be slower to get starry-eyed. “I think women unconsciously postpone love compared to men. Women have a lot more to lose reproductively by committing to the wrong man. They are born with a finite number of eggs, yet men produce millions of sperm on a daily basis.”

In other words, women have to be a lot more careful who they mate with than men do. “If women commit to and get pregnant by an unworthy mate [with] no help rearing a child, that would be very costly, time- and resource-wise.”

Easy come, easy go

But before you get too comfortable, consider this: while men might fall in love faster than women do, they tend to fall out of love faster, too. Psychologist Ingrid Collins says that in her experience, “men are far more inclined to get fired up about a mate, but are also more likely to look around more.”

This makes sense, when you consider that the male of the species is typically the hunter, continuing to prowl around while the female rears the young.

Lamont says men may say “I love you” sooner because in general, they’re more likely to be risk-takers. “Revealing to your significant other that you love them risks vulnerability, because we can never be entirely sure they feel the same,” he explains. Since men are taught to be domineering and assertive, they may feel more comfortable taking that leap. Just remember that he’s probably going to continue to look around, and those early sparks of love may end up being just a flash in the pan.

Let’s talk about sex, baby

So, what makes an initial rush of love turn into something that’s likely to last a lifetime? Researchers say it’s a combination of factors. One of those is great sex. While some may brush sexual attraction off as unimportant in the long run, Dr Helen Fisher, an anthropologist who studies romance and relationships, says it’s vital to helping people fall – and stay – in love.

“When you have orgasm, you get a real flood of oxytocin and vasopressin. And these are the basic bodily and brain systems for attachment,” Fisher explained on a recent episode of the On Being podcast. So, if you have great sex and continue to have it, you’ll keep upping that level of attachment – which could keep your hunter from prowling around for another mate.

We’re all looking for the same thing

While sex fosters intimacy, which is a key factor in solidifying a couple’s bond, it’s not the only ingredient in lasting love. Men, just like women, ultimately want to feel supported and understood. Fisher, who works with Match.com as an analyst, says men and women are essentially looking for the same thing.

“They must have somebody they can trust and confide in. They must have somebody who respects them. They must have somebody who makes them laugh, which actually is very important biologically…laughter drives up the dopamine system. It’s very good for you, ” Fisher says.

So, when my boyfriend said he was falling deeper in love with me, even though he’d already told me he loved me, it probably meant that although we’d had an instant attraction and both been infatuated with each other, the subsequent months we spent making each other laugh, confiding in each other, and having incredibly hot sex cemented our bond even further, making his love stronger.
