Why the idea that good sex “just happens” is keeping couples stuck — and what to do instead.
It was a Tuesday night in early fall. Maya and her partner Jonah had finally gotten the kids to bed, poured two very necessary glasses of wine, and collapsed onto the couch. They were both tired. They were always tired. And somewhere in the silence, Maya thought: we used to just want each other. It used to be easy. What happened to us?
What happened, most likely, is the spontaneity myth. And it has quietly convinced more couples that their relationship is broken than almost anything else we see in sex therapy.
Here’s the thing nobody tells you: your sex life was never actually that spontaneous. What felt effortless in the beginning was, in fact, beautifully invisible effort. And once you see that clearly, everything changes.
The Short Answer
Good sexual desire doesn’t appear out of thin air — it gets created. Early in relationships, couples invest enormous time, energy, and anticipation into building toward intimacy without realizing they’re doing it. As relationships settle into real life, that invisible investment drops off, and desire seems to vanish with it. The solution isn’t to wait for the spontaneity to return. It’s to start building toward desire intentionally again.
Who This Post Is For
This is for anyone who finds themselves thinking “it used to just happen” and can’t figure out why it doesn’t anymore. It’s for couples who feel vaguely broken by the idea of scheduling intimacy, or who have tried to “be more spontaneous” and found it doesn’t work. It’s also for the partner who is waiting to feel desire before initiating — and waiting, and waiting.
Let’s Rewind to When Sex Was “Spontaneous”
Think back to the early days of your relationship. Cast your mind back to one of those encounters that felt so electric, so immediate, so perfectly unplanned.
Now let’s trace what actually happened.
You made plans to see each other — probably days in advance. You thought about them in the time leading up to it. Maybe you fantasized a little. On the day itself, you chose your outfit with some care. You showered. You did the thing with your hair. You texted them something flirty on the way over. You arrived already lit up — nervous, anticipating, curious. Your nervous system had been building toward that moment for hours, possibly the whole week.
That is not spontaneity. That is purposeful, sustained, invisible priming. You were stoking desire long before any physical contact happened.
As relationships deepen, most of that scaffolding quietly falls away. You already know this person. Dinner plans get made an hour before. The flirty texts are replaced with “can you pick up oat milk?” The mental energy that used to go toward anticipation is now going toward school pickups and the thing you forgot to do at work. And then we wonder why the electricity feels different.
It’s not that desire disappeared. It’s that the conditions that were generating it stopped being tended.
The Cultural Lie We’ve All Swallowed
The spontaneity myth is not just a private misunderstanding. It’s actively everywhere. Movies, television, every glossy magazine at a Loblaws checkout — they all sell the same image of desire as something that strikes like lightning, unprompted and unearned. Two people look at each other across a crowded room and the chemistry is instant and obvious and requires exactly zero effort to maintain.
This sets couples up to fail. When real-life intimacy starts to require effort, context, and communication, people read that as evidence that the relationship has lost its magic — rather than evidence that it has grown into something mature that needs a different kind of tending.
The myth also leaves very little room for the way most people in long-term relationships actually experience desire. Which brings us to something important.
Spontaneous Desire vs. Responsive Desire: The Distinction That Changes Everything
Spontaneous desire is what we tend to picture when we imagine sexual desire: it appears seemingly out of nowhere, unprompted, before any sexual context is present. You’re walking on the Danforth, see a stranger, and feel a pull. Many people — particularly early in relationships — experience desire this way.
Responsive desire is different. It emerges in response to something: a touch, closeness, an emotionally intimate moment, or simply a context that signals safety and connection. Your body doesn’t lead with wanting — it follows with wanting once pleasurable things are already underway.
Sex researcher Emily Nagoski, who has written extensively on this distinction, points out that responsive desire is not broken desire. It’s not low desire. It’s simply a different pathway to the same destination. Many people in long-term relationships find that their desire shifts from spontaneous to responsive over time — and if they don’t know this is a perfectly normal and valid way to experience desire, they conclude something is terribly wrong.
The person who waits to feel turned on before initiating anything may wait indefinitely. The person who understands responsive desire knows that sometimes you start moving toward intimacy first, and the wanting follows.
A Note on ADHD, Novelty, and Desire
At Horizon, we work with a lot of neurodivergent couples, and the spontaneity myth plays out in a particularly interesting way when ADHD is part of the picture. People with ADHD often experience what’s sometimes called novelty-driven desire — the dopamine system that drives wanting is strongly activated by newness, excitement, and the unknown. In the early stages of a relationship, when everything is fresh and uncharted, desire can feel almost overwhelming. Once the relationship becomes familiar, that same system may go very quiet.
This isn’t a loss of attraction. It’s how the ADHD nervous system is wired. And knowing that means couples can design for it — building novelty intentionally rather than waiting for it to show up on its own.
The Canadian Research Worth Knowing
A national study of 2,400 Canadians found that low sexual desire was the single most commonly reported sexual concern — and that it was directly correlated with being in a long-term relationship. This tells us something important: desire doesn’t fade because relationships go wrong. It fades because relationships become familiar, comfortable, and real. That’s not a tragedy. That’s an invitation.
So What Do You Do Instead?
The good news is that once you let go of the spontaneity myth, something more interesting opens up: the possibility of deliberately creating the conditions for desire. Here’s what that can look like in practice.
Flirt like you used to. Not just on evenings when sex is on the table, but as a regular texture of your relationship. A text that says you’ve been thinking about them. A lingering look at dinner. These are deposits that build charge over time, and they’re exactly what you used to do without realizing it.
Make date nights actually non-negotiable. Not as a gateway to sex, but as protected time where you’re fully present with each other without managing logistics. Whether that’s a walk along the Beltline trail or a proper dinner on St. Clair, what matters is that you prioritize it. Put it in the calendar. Treat it like a work commitment.
Steep before you meet. Think of desire like tea. A bag dropped in water for ten seconds gives you very little. But let it steep — warmth, time, attention — and it transforms. Start building toward intimacy earlier in the day. Think about your partner. Imagine the evening. Let the wanting accumulate.
Stop waiting to feel desire before initiating. If you have responsive desire, trying before you feel ready is not fake — it’s how your particular system works. Your body may need to be in motion before it joins the party.
Embrace the schedule. Yes, scheduling sex feels deeply unsexy until you reframe it. You schedule exercise because it won’t happen otherwise. You book time with friends because spontaneous catch-ups stopped happening after your late twenties. Scheduling intimacy is an act of prioritisation. It says this matters enough to protect. And when a date is in the calendar, you can start steeping days in advance.

FAQ’s About Sex & Spontaneity
Yes — this is responsive desire, and it’s completely normal and valid. Many people, particularly in established relationships, experience desire as something that follows arousal rather than precedes it. You don’t need to wait to feel turned on before initiating. Starting often creates the wanting.
The first few times often feel awkward — that’s normal. You’re building a new groove. The awkwardness usually settles once you stop waiting for it to feel like early-relationship spontaneity and start accepting that intentional intimacy has its own quality. Many couples find it becomes something they genuinely look forward to once the pressure comes down.
You might share what you’ve learned about responsive desire — that for many people, desire follows rather than leads. And you might ask what specifically feels off about scheduling: often the concern is less about scheduling itself and more about the fear that planned sex will feel obligatory or joyless, which is worth exploring together.
Almost certainly not. Desire levels vary between people, and the gap often feels larger than it is when one partner has spontaneous desire and the other has responsive desire — because the spontaneous-desire partner keeps initiating and the responsive-desire partner keeps not being ready yet. Understanding this distinction often takes a huge amount of pressure off both people.
This is worth exploring gently, and it’s one of those questions that sex therapy is genuinely built for. It may mean you have responsive desire and the current relational conditions aren’t creating the right context. It may point to something worth examining about the relationship dynamic or your own history with intimacy. Neither possibility is cause for shame — both are worth understanding.
Pushing rarely helps and often creates more withdrawal. “I don’t know” is usually an honest answer — many people genuinely can’t access why their desire has dropped. What helps more is getting curious together about conditions rather than reasons: What would need to be different for you to feel more interested? What feels in the way right now? These questions open doors that “why don’t you want me?” tends to close.
It’s not too long. Extended periods of sexual disconnection can create their own particular anxiety — the gap starts to feel like something that needs to be addressed all at once, which makes the first step feel enormous. Sex therapy in Toronto is especially helpful in these situations because it provides a structured, supported path back that doesn’t require one big leap. Small, low-pressure steps rebuild the bridge.
Yes — asexuality is a real and valid sexual orientation, describing people who experience little or no sexual attraction. It exists on a spectrum, and it’s distinct from low desire caused by stress, hormones, or relationship dynamics. If your partner genuinely identifies this way, the conversation shifts from “how do we fix this” to “how do we build an intimate life that works for both of us” — which is a different and very workable question with the right support.
This is one of the harder questions and also one of the most important to take seriously. It may point to unresolved resentment or emotional disconnection that’s closed down desire specifically within the relationship. It may point to something worth examining about compatibility or history. It may also simply be about context — if the relationship has become a high-stress environment, the brain understandably doesn’t associate it with pleasure. In sex therapy, we can help you figure out which of these is closer to true.
By remembering that everything good in a long-term relationship takes work — communication, friendship, parenting, trust. Sex is not exempt from that, and there’s nothing romantic about pretending it should be. Couples who have great intimate lives in long-term relationships aren’t the ones who got lucky. They’re the ones who decided their connection was worth tending. That’s actually more romantic than the myth.
