Most long-term couples have sex between once a week and once a month, according to research published in the Archives of Sexual Behavior analyzing data from over 26,000 people. But frequency alone tells you almost nothing about whether your relationship is healthy or satisfying. What matters more is whether both partners feel connected, respected, and reasonably content with the rhythm you’ve found together, even when that rhythm changes.
Why “Normal” Is the Wrong Question (But Everyone Asks It Anyway)
You’re lying in bed at 11 p.m., scrolling, wondering if other couples are doing it more than you are. Maybe it’s been three weeks. Maybe it’s been three months. Maybe your partner initiated tonight and you pretended to be asleep, and now you feel guilty and confused about why you keep saying no to something you used to want.
The question “what is normal?” feels urgent because we use it as a proxy for “are we okay?” But intimacy frequency is one of the most variable aspects of coupledom. The Kinsey Institute’s 2023 survey found that 18% of coupled adults have sex a few times per year or not at all, 25% have sex once or twice a month, 34% have sex two to three times per month, and 23% have sex once a week or more. That’s a huge range, and all of those couples include people who describe their relationships as happy.
What researchers like John Gottman and Emily Nagoski consistently find is that satisfaction depends far more on whether the frequency matches what both people actually want, and whether the lower-desire partner feels pressured or the higher-desire partner feels rejected. A couple having sex twice a month who both feel good about it is in better shape than a couple having sex twice a week where one person is performing out of obligation.
What Changes Frequency (and Why That’s Not a Crisis)
Intimacy ebbs and flows for dozens of reasons, most of them completely ordinary. New parents, according to research from the Gottman Institute, report a 40-70% drop in sexual frequency in the first year postpartum. People in perimenopause often experience shifts in desire due to hormonal changes. Work stress, caregiving for aging parents, anxiety, antidepressants, sleep deprivation, unresolved conflict, and simple routine all affect how often you feel like having sex.
Emily Nagoski’s research on spontaneous versus responsive desire explains why so many long-term couples struggle: about 75% of men and 15% of women experience spontaneous desire (wanting sex out of the blue), while the majority of women and some men experience responsive desire (wanting sex only after arousal begins). In new relationships, novelty creates arousal easily. In year seven, when you’re both tired and wearing old T-shirts, responsive desire needs more intentional context. That’s not dysfunction. That’s how most human bodies work.
If frequency has dropped and one or both of you miss the connection, that’s worth addressing. But the drop itself is not evidence that something is broken.
Four Moves to Find a Rhythm That Works for Both of You
Name what you actually miss, not just the number
Instead of “we never have sex anymore,” try getting specific about what you’re missing. Is it feeling wanted? Physical closeness? Playfulness? A break from being responsible? The lower-desire partner often feels defensive when the conversation is framed as “you’re withholding,” but can engage when it’s framed as “I miss feeling close to you.” Try: “I’ve noticed we haven’t been physical much lately, and I miss that feeling of being on the same team. Can we talk about what would feel good for both of us right now?”
Check in about context, not just frequency
Responsive desire needs the right conditions. Dr. Lori Brotto’s research on sexual concordance shows that desire often follows arousal, not the other way around. Ask each other: What makes you feel open to intimacy? What shuts it down? For many people, it’s not about finding more time but about reducing friction: resentment from unequal household labor, feeling touched-out from small children, needing 20 minutes of transition time after work, wanting to feel like a person and not just a co-parent. One partner might say: “I think I need us to talk without screens for ten minutes before bed, not because that leads to sex, but because I feel like a stranger otherwise.”
Experiment with a menu, not a script
Many couples get stuck because “intimacy” has narrowed to one definition: intercourse, in bed, at night, when both people are already exhausted. Broaden the menu. Make out on the couch for ten minutes with no expectation it goes further. Take a shower together. Trade massages. Schedule a Saturday morning when you’re both rested instead of trying at 10 p.m. when one of you is already half asleep. The lower-desire partner often feels more open when the pressure to perform is off the table. Try: “What if we planned an hour on Sunday where we’re just physical, however that feels good, with no agenda?”
Protect connection outside the bedroom
Gottman’s research on marital stability found that couples who maintain friendship, turn toward each other’s bids for attention, and repair after conflict have better sex lives than couples who only focus on sex itself. If you’re living like efficient roommates during the day, it’s hard to flip a switch at night. Small daily moments matter: six-second kisses when you get home, asking real questions instead of logistics, putting the phone down when your partner is talking. These aren’t foreplay. They’re the foundation that makes desire possible.
When to Worry (and When Not To)
A drop in frequency is not automatically a red flag. What does warrant attention: if one partner feels coerced or is having sex they don’t want, if avoidance has become the primary dynamic, if there’s underlying pain or dysfunction that hasn’t been assessed, or if the intimacy gap is creating resentment that’s bleeding into the rest of the relationship.
If you’ve tried the moves above for a few months and nothing shifts, or if the conversation itself feels impossible, that’s when working with a sex therapist or couples counselor trained in intimacy issues can help. AASECT-certified therapists specialize in this exact terrain. If physical pain is involved, a pelvic floor physical therapist or a gynecologist familiar with sexual health should be part of the conversation.
But if you’re simply in a phase where intimacy is less frequent and you’re both okay with it, or if you’re working together to adjust and the effort itself feels connecting, you’re probably doing just fine. Normal is not a number. It’s a negotiation that keeps evolving.
Frequently Asked Questions
How often do most married couples have sex?
Research from the General Social Survey and the Archives of Sexual Behavior shows that married couples in the U.S. have sex on average 50 to 60 times per year, which works out to roughly once a week. However, that average includes a wide range: some couples have sex multiple times per week, others once a month or less. Age, health, stress, and relationship satisfaction all influence frequency more than marital status itself.
Is it normal for intimacy to decrease over time?
Yes. Nearly all long-term relationships experience a decline in sexual frequency after the first two years, according to research on relationship stages and desire. This happens because novelty and newness naturally boost arousal, and because life accumulates: children, work demands, aging, routine. The decline is normal, but it doesn’t have to mean disconnection. Couples who adapt by being intentional about intimacy and maintaining emotional closeness often report high satisfaction even with lower frequency.
What if my partner wants sex more often than I do?
Desire discrepancy is one of the most common issues in long-term relationships, and it doesn’t mean anyone is broken. Start by talking about what each of you actually needs: is it orgasm, closeness, stress relief, feeling desired? Sometimes the higher-desire partner is satisfied with other forms of physical affection, and sometimes the lower-desire partner finds they’re more open when pressure is removed and context improves. A sex therapist can help you navigate this without shame on either side.
Can a relationship survive without much physical intimacy?
Some relationships thrive with very little sexual intimacy, especially if both partners are on the same page and other forms of connection are strong. Research on asexual individuals and low-libido partnerships shows that affection, communication, shared purpose, and respect matter more to long-term stability than frequency of sex. Problems arise when there’s a mismatch in expectations or when lack of intimacy reflects avoidance or unresolved conflict, not when a couple has simply found a rhythm that works for them.
When should we see a therapist about our sex life?
Consider seeing a therapist if you’ve tried adjusting on your own for several months without progress, if the intimacy gap is creating ongoing resentment or distance, if one partner feels pressured or the other feels constantly rejected, or if there’s pain, dysfunction, or trauma involved. An AASECT-certified sex therapist or a couples counselor trained in intimacy work can offer tools and perspective that are hard to find on your own. Seeking help early, before patterns harden, usually makes the process easier.
A Small Step Forward
If this article has surfaced something you’ve been avoiding talking about, the most useful thing you can do this week is name it out loud with your partner, without blame. You don’t need to solve it tonight. You just need to start the conversation in a way that makes both of you feel safe.
If you’re looking for a resource to explore together, the book Come As You Are by Emily Nagoski offers a compassionate, evidence-based look at how desire actually works, especially for partners with responsive desire.
