Most couples don’t lose intimacy all at once. It happens slowly, in the gaps between busy days, until one or both partners realize it’s been a while since they felt truly close.
There’s actually a framework for understanding how intimacy builds, and it comes from an unexpected source. In 1971, a zoologist named Desmond Morris studied why some couples stayed together while others split up. He noticed a pattern: long-lasting couples tended to move through roughly the same 12 stages of physical closeness, starting with a glance across a room and ending with sex, without rushing any of them. Couples who skipped ahead tended to have weaker relationships and split up more often.
Even though the stages are physical, each one carries emotional weight, which is why skipping them changes more than people expect.
Here’s what the 12 stages actually look like
A few of these will feel familiar, and a couple might catch you off guard.
1. Eye to body. This is the first read you get on someone, before any words are exchanged. You notice how they carry themselves, their approachability, and if something about that draws your attention. It may feel passive, but it’s actually where interest starts, or doesn’t.
2. Eye to eye. Eye contact comes next, and it’s more loaded than it seems. The first time two people really look at each other, something gets acknowledged, even if neither person could say exactly what.
3. Voice to voice. Then comes the first real conversation. How someone talks, what they bring up, whether they seem curious about you, all of it registers here, often without either person realizing they’re taking notes.
These three stages occur constantly in everyday life, making them easy to dismiss. But skip them, and you can end up on a date with someone you’ve messaged for weeks and never actually built any ease with, which is part of why so many first dates feel stiff.
4. Hand to hand. The first physical contact, usually a touch on the arm or holding hands, is small but rarely feels small in the moment. The slight nervousness that often comes with it is a sign that the moment is registered.
5. Hand to shoulder. An arm around the shoulder signals familiarity, maybe a little protectiveness. There’s an ease to it that wasn’t there a stage ago.
6. Hand to waist. Pulling someone in by the waist is more deliberate. Morris noted that couples at this stage usually know each other well enough that the gesture feels natural rather than forced.
7. Face to face. Hugging and kissing fall here, and this is where the emotional buildup from earlier stages starts to show up physically.
8. Hand to head. Cradling someone’s face, running fingers through their hair, resting a head on someone’s shoulder. These gestures often get overlooked, but Morris considered this one of the more significant stages. It takes a kind of trust that can’t really be faked, only built.
9 through 12. The remaining stages move into more explicit physical intimacy, ending with sex. Morris framed sex less as a destination and more as the natural outcome of everything that came before it, which is part of why it can feel hollow when the earlier stages got skipped, even between people who’ve been together a long time.
For long-term couples too
This framework is most often used for dating, as a kind of pace check. But the more interesting application might be for couples who’ve been together for years, since long-term relationships tend to lose the early stages first.
Life gets busy, and the small things, like holding hands or a hug before work, are the first things to go. What’s often left is a jump from no physical contact straight to sex, with everything in between skipped. This leaves couples wondering why sex feels disconnected or why they’re starting to feel more like roommates and less like partners.
Morris found that couples who made a point of revisiting the earlier stages tended to report stronger bonds overall. A simple way to check in is to ask what you and your partner actually did this week to build closeness, and where things got skipped.
Attachment style factors into this, too. Those with an avoidant style are much more likely to rush past or skip the more vulnerable, middle stages, while those with an anxious attachment style can sometimes push toward closeness faster than their partner is ready for, often coming across as pressure. Either way, recognizing your own pattern makes it easier to understand where and when a disconnect might be occurring.
What slowing down actually looks like
In practice, this rarely means a big romantic gesture. It might simply be putting your phone down at dinner and making eye contact, or letting a hug at the door last a little longer than you’re used to. These moments don’t require much other than attention, which, as we know, can be one of the first things to go once a relationship settles into a routine.
Research supports this idea as well. A 2024 study by Syracuse University found that something as simple as holding hands can lower stress and increase a sense of security between partners, echoing what Morris described years earlier.
