Why You Need to Practice Sex Too: The Science of Relational Fitness

Why You Need to Practice Sex Too: The Science of Relational Fitness

We treat the gym like a second job. We track our macros, measure our REM cycles, and obsess over whether we’re hitting our 10,000 steps, yet when it comes to the most intimate part of our lives, we just... expect it to work. It’s weird, honestly. We assume that sexual chemistry is this magical, infinite resource that either exists or it doesn't. But the reality is a lot more practical. If you want to be good at something—anything—you have to do it. You have to refine it. Basically, you need to practice sex too if you want a long-term connection that doesn’t just fizzle out into "roommate syndrome."

Think about it. You wouldn't expect to run a marathon without training. You wouldn't expect to play a Rachmaninoff concerto because you feel "inspired." Sex is a physical, emotional, and neurological skill set. It involves coordination, cardiovascular health, and a massive amount of communication. When we stop viewing sex as a spontaneous explosion of lust and start viewing it as a practice, the pressure drops. Suddenly, it’s not about performing; it’s about getting better at being together.

The Myth of Spontaneous Desire

Most of us grew up on a diet of romantic comedies where two people lock eyes and suddenly they’re tearing each other's clothes off in a rainstorm. That’s "spontaneous desire." It’s great. It’s also mostly a phase. Dr. Emily Nagoski, author of the groundbreaking book Come As You Are, talks extensively about the difference between spontaneous and responsive desire.

For many people—especially those in long-term relationships—desire doesn't just show up uninvited. It needs an invitation. It needs a context. This is where the idea that you need to practice sex too becomes vital. If you wait until you're "in the mood" to initiate, you might be waiting until the next solar eclipse. Practice creates the context. It’s about showing up even when you’re not 100% "raring to go," knowing that once you start, the physical sensations will likely trigger the mental desire.

It sounds unromantic to some. "Scheduled sex? Gross." But honestly, what’s more unromantic? Scheduling time to prioritize your partner's pleasure, or going six months without touching each other because you were both too tired or busy watching Netflix?

Your Brain on the "Practice" of Intimacy

When we talk about practice, we’re talking about neuroplasticity. Your brain builds pathways based on what you do frequently. If you go months without sexual intimacy, those neural pathways start to gather dust. On the flip side, regular physical connection keeps the endocrine system primed.

Oxytocin—often called the "cuddle hormone"—is released during touch and orgasm. It lowers cortisol. It makes you feel safe. If you haven’t had a hit of oxytocin in a while, you might find yourself snapping at your partner over the dishes. You're not actually mad about the dishwasher; you're just biologically disconnected. By leaning into the idea that you need to practice sex too, you are essentially performing maintenance on your relationship’s biological foundation.

  • The Prolactin Factor: After orgasm, the body releases prolactin, which helps with sleep and relaxation.
  • The Testosterone Loop: It’s a bit of a "use it or lose it" situation. Regular sexual activity can help maintain healthy hormonal balances in both men and women.
  • Blood Flow: It’s a physical act. Like any exercise, regular activity improves circulation to the pelvic region, which actually makes the physical experience better over time.

Why Technical Skill Actually Matters

We don’t talk enough about the "skill" part. Everyone has different "buttons." What worked for an ex might be a total turn-off for a current partner. You can’t learn someone’s body in a night. Or a week. It takes years of trial and error.

Practice is where the "error" part becomes okay. When you’re "practicing," a clumsy moment isn’t a mood-killer; it’s just part of the session. You learn the nuances of pressure, rhythm, and timing. You learn how to breathe together. This is especially true as bodies age. What worked at 25 might not work at 45 or 65. If you aren't in a state of constant "practice" and adaptation, these physical shifts can feel like the end of your sex life rather than just a change in the weather.

Breaking the "Performance" Mindset

One of the biggest hurdles to a healthy sex life is the "spectatoring" effect. This is a term used in sex therapy where a person is so focused on how they look or whether they’re performing "correctly" that they completely disconnect from the actual sensation.

When you adopt the mindset that you need to practice sex too, the goal shifts. You aren't trying to win an Olympic gold medal in bed. You’re just... practicing. Like a yoga practice. Sometimes your balance is off. Sometimes you’re not flexible. Sometimes you just fall over. That’s fine. The value is in the showing up, not the "perfect" execution.

This shift is huge for people dealing with erectile dysfunction or orgrastic difficulties. If the goal is "perfection," failure is devastating. If the goal is "practice," then a "failed" encounter is just more data for next time. It takes the teeth out of the anxiety.

The Role of Vulnerability and Communication

You can’t practice sex in a vacuum. You have to talk about it. And talking about sex is, for many people, significantly harder than actually having it.

"I like it when you do X," or "Actually, Y doesn't feel that great today." These are hard sentences to say! They feel like criticisms, even when they aren't. But in a "practice" framework, feedback is essential. Coaches give feedback. Partners in a practice should too.

Research from the Gottman Institute suggests that couples who talk openly about their sex lives report much higher satisfaction. It’s not because they’re doing anything wilder than anyone else; it’s because they’ve built the "communication muscle." They’ve practiced the vulnerability.

Actionable Steps to Improve Your "Relational Fitness"

So, how do you actually put this into play without it feeling like a chore? It’s about small, consistent shifts rather than a total overhaul.

1. Redefine "Sex"
If your definition of sex is only "penetration leading to dual orgasms," your practice is going to be limited and high-pressure. Broaden the scope. Manual stimulation, heavy petting, or even just long-form naked cuddling counts as practice. It keeps the "erotic field" active.

2. The 15-Minute Rule
Sometimes the hardest part is starting. Commit to 15 minutes of physical intimacy. If, after 15 minutes, you’re still not feeling it, you can stop. No guilt. Most of the time, the "practice" will take over and you’ll want to continue.

3. Body Mapping
Spend time—without the goal of orgasm—just exploring where your partner is sensitive. Use different textures, different pressures. This is literal practice. It builds a map of your partner's current nervous system, which changes based on stress, cycle, or age.

4. External Resources
Don't be afraid to look at the "manual." Books like The New Joy of Sex or apps like Zane or OMGYES (which uses actual data-driven research on female pleasure) can provide "drills" for your practice. It sounds clinical, but it’s actually incredibly empowering to have new techniques to try.

5. Prioritize the "Afterglow"
The 10 minutes after sex are as important as the act itself. This is when the oxytocin is peaking. Practice staying connected—physically touching, talking, or just breathing—instead of immediately reaching for your phone or rolling over to sleep. This "cool down" reinforces the bond you just practiced.

Acknowledging the Hard Parts

Let's be real: some seasons of life make "practice" feel impossible. New parenthood, grief, intense career stress, or chronic illness can all tank your libido. In these moments, the "practice" might just be a 30-second hug or holding hands while watching a movie. That counts.

The danger isn't in having a "dry spell." The danger is in deciding that the dry spell is the new permanent reality. By maintaining the mindset that you need to practice sex too, you keep the door cracked open. You acknowledge that while the pilot light might be low, the stove is still hooked up to the gas.

Ultimately, sexual intimacy is a language. If you don't speak it for ten years, you’re going to lose your fluency. You’ll forget the grammar. You’ll stumble over the words. But if you keep speaking it—even if you're just stuttering through some basic phrases once a week—you stay fluent. You stay connected. You stay "fit."

Start by changing the narrative. Move away from the idea that sex is something that "happens" to you when the stars align. Move toward the idea that sex is a beautiful, complex, and rewarding skill that you and your partner choose to hone together. It’s not work; it’s a workout for the soul.

Take the pressure off the "event" and put the focus on the "habit." Sit down with your partner. Be honest. Tell them you want to "get back into training." You might find that the simple act of acknowledging the need for practice is the very thing that jumpstarts the spark you thought was gone.

Establish a "low-stakes" night this week. No expectations of a "grand finale." Just focus on the touch, the sensation, and the presence. That's where the real growth happens. That's how you build a sex life that lasts a lifetime.
