5 Ways To Spark Sexual Chemistry That Actually Lasts

In the guide below, you'll discover what sexual chemistry really is, 3 clear signs of sexual chemistry, and 5 ways to build sexual chemistry with your partner.

What Exactly Is Sexual Chemistry?

Sexual chemistry is a bit of a slippery concept, and it gets defined differently depending on who you ask...

Wanting sex – Some people equate it with the sheer desire to sleep with someone, or the sense of mutual sexual pull between two people.

Being sexually compatible – Others frame it more around sexual compatibility. To them, chemistry is inherently a two-way street.

It's not simply about you wanting someone but them wanting you back — and both of you being conscious of that mutual pull.

What science has to say – Even researchers find it slippery to pin down, with one paper describing it as

…nonspecific, subjective description of a mysterious, physical, emotional and sexual state that feels driven and mostly pleasurable existing in the context of an interpersonal relationship… [1]

What does that actually mean, though?

Basically, you'll recognize it when it hits you. Luckily, pop culture gives us no shortage of examples — Titanic, New Girl, Fleabag, and Pride & Prejudice all showcase it well.

Bodily sensations – Sexual chemistry typically registers physically, somewhere between nervous jitters and pure excitement. Ever locked eyes with someone across a crowded bar and simply couldn't tear your gaze away? That's chemistry in action! Likewise, a kiss loaded with chemistry might send shivers through you, while one lacking it leaves you feeling nothing at all.

Something instinctive – For some, chemistry might just be an instinctive reaction that happens without explanation. We still don't fully understand what triggers powerful chemistry with a given person — pheromones or some unconscious chemical pull might be involved.

Chemistry can stem from your actual attractions, what society has conditioned you to find appealing, or even from someone reminding you of a person or thing tied to sexuality — or simply feeling comforting on some level [2]. Some call this the "spark." When it's this kind of instinctive pull, building it from scratch may not be realistic.

Depending on how you define sexual chemistry personally, you might refuse to date or sleep with someone unless you sense it right away. That makes chemistry a pretty big deal for a lot of people!

But if you're more open-minded, a lack of instant chemistry doesn't necessarily have to be a dealbreaker if you're willing to cultivate it.

In fact, chemistry might not surface immediately if you identify as demisexual, meaning sexual attraction only kicks in once you've built real emotional closeness with someone.

And What About Sexual Tension?

Chemistry and tension tend to travel together. Depending on how you define sexual chemistry, tension might feel like a totally separate thing, might overlap substantially, or might always show up hand-in-hand with chemistry for you.

Sexual tension arises when you're anticipating something sexual with someone, typically in situations where acting on it isn't an option. This kind of tension can build naturally when you meet someone with whom you have chemistry but no chance to do anything about it — think office settings.

You can also deliberately build sexual tension with a partner — which might be necessary if the bedroom has gotten a little routine — through anticipation or teasing your partner.

How Much Does Sexual Chemistry Actually Matter?

As with most things, it depends. You wouldn't be alone in believing chemistry matters more for great sex than even orgasm itself. Some people see chemistry as merely one ingredient among several for great sex [2]. Others treat it as a welcome extra.

One quick note before moving on. Sexual chemistry can absolutely make for fantastic sex.

That said...

Chemistry by itself isn't a solid enough foundation for an entire relationship. Don't let yourself get swept into something without a future just because the physical pull is intense.

Coming up, we'll cover how to actually build strong sexual chemistry.

3 Signs You've Got Sexual Chemistry

Watch for these telltale signs of chemistry so you don't miss the opportunity to act on it (should you want to).

1. Sexual Attraction

Sexual attraction is one of the clearest markers of chemistry, and can look like:

• Feeling turned on by someone. 11 tips for getting horny.
• Picturing them while masturbating. 14 powerful masturbation techniques for women.
• Craving sex with them.
• Genuinely enjoying sex with that person. How to deeply enjoy sex.
• Getting distracted by sexual thoughts about them.

2. Sexual Tension

Tension is another marker of chemistry. It's usually the enjoyable kind of tension, since you both feel it simultaneously. There's a bit of nervousness mixed with real excitement and arousal. Your pulse might quicken, or you may get butterflies. Arousal might even build physically.

Once you finally act on it, expect fireworks! That's part of what makes sexual tension worthwhile.

3. Signs the Chemistry Goes Both Ways

Wondering if the other person feels it too? Look out for:

• Prolonged eye contact
• Mirrored body language. How to read your partner's body language.
• Physical touch
• Flirting – How to tell if a guy is flirting with you.

And hey, you can always just ask directly! If you're fairly confident, try something like "Do you feel what I feel?" to test the waters and confirm mutual chemistry.

Plus, these same behaviors work in reverse to signal your own interest.

7 Signs Sexual Chemistry Is Missing

Without sexual chemistry, you'll miss out on the signs above and might just feel indifferent or "meh" about someone. But you could also notice other, more active signals, such as:

1. Rarely if ever thinking about the person
2. Feeling turned off by them, whether that's the "ick" or a physical aversion
3. Loving your partner without being in love with them
4. Sensing that the spark has faded
5. Struggling to get aroused even thinking about them
6. Being unable to picture them in your sexual fantasies
7. Sensing something's missing, dull, or off... even if they're genuinely lovely or "great on paper"

Now let's get into building it!

How to Build Sexual Chemistry – 5 Approaches

If there's even a flicker of a spark between you two, you can likely grow it further. And if the chemistry used to be strong but has faded lately, there's still hope for you as well!

1. Keep Your Curiosity Alive

Resist assuming you've got this person completely figured out, or that they'll mirror everyone you've been with before. Lean on past experience as a baseline, but assume everyone brings something distinct to the table... and commit to uncovering it!

Keep in mind that pleasure extends well beyond orgasm alone, so figure out what feels good to them even when it's not leading to climax.

Discovering what someone enjoys in bed helps cultivate real chemistry, particularly when your interests overlap with theirs. Build an environment where your partner feels safe discussing their fantasies openly (this guide to sexual communication can help).

Staying curious about sex also lowers the odds you'll get bored and stuck in a rut. Exploring different partners might teach you something about yourself too, so make an effort to learn more about what turns you on and feels good to you personally. This guide to masturbating in the shower or some hot sex stories could be a good starting point.

And make sure to share whatever you discover with your partner!

2. Loosen Up and Let Go

Feeling comfortable enough to do, say, or request whatever you want matters a lot for chemistry to take hold.

Struggling to let go can make building intense chemistry difficult, since you generally need to be authentically yourself and vulnerable to actually feel it. Get too caught up worrying about how you look or sound, or whether someone's into you (or into sex with you), and truly letting go becomes nearly impossible. Same goes for fixating on whether your (or your partner's) preferences are "weird" or socially unacceptable.

Similarly, struggling to let go around someone you don't trust can make it tough to build chemistry during casual sex or one-night stands. That's completely normal and pretty common — plenty of people need trust before they can truly let loose.

Trust doesn't require a serious or long-term relationship, either. Sometimes it just means knowing your partner well enough to feel safe letting go for one night. Agreeing on a safe word, especially during kinkier activities or rougher sex, can make it easier to let go.

3. Picture It in Your Mind

Visualization is another way to build chemistry. Picture yourself in a sexual moment with this person. See yourself as confident, sexy, and desirable. Some creative license is fine, but keep it grounded in reality.

4. Discover Your Roles

Finding your roles doesn't necessarily mean formal role play. You can simply lean into your natural tendencies and desires. For instance, if you're naturally more dominant and your partner leans submissive, you might take the lead in bed. Ask your partner to worship your body so you feel like a goddess, or if you're the less experienced one, let your partner guide the way.

Learn: How to become more dominant during sex or how to explore your submissive side.

Of course, if you'd rather go all in with costumes, scripted lines, and props, go for it! Check out these 42 ideas for role playing if you need inspiration.

5. Make Smart Use of Time and Distance

Finally, work with your circumstances rather than against them. Time spent apart — whether from school, work across town, separate living situations, or a long-distance setup — can actually intensify sexual chemistry!

A sultry kiss before parting ways in the morning, or a well-timed sexy text, can keep chemistry and tension simmering all day until you're finally reunited. And if the separation spans hours or entire miles, you might find the chemistry runs hot by default, whether or not you're physically together.

That said, building chemistry gets harder if either of you is distracted or stressed out.

As mentioned earlier, the answer to "Can sexual chemistry grow over time?" might genuinely be "No" for some people. But that won't necessarily hold true for every partner or every situation.

Maybe You Should Be Searching for Sexual Connection Instead

Follow the advice above and you might land yourself some fantastic chemistry. But if you give it a real shot and still can't detect any spark, you might be approaching the whole thing wrong.

Rather than trying to manufacture chemistry, you may be better off seeking it out from the start.

What does that look like in practice?

Seek out people who are drawn to — or at least open to trying — the same kinds of sexual activities you enjoy, whether that's slow sex or BDSM.

Prioritize partners who place a similar value on sex as you do. Couples where both people either genuinely prioritize sex or both don't tend to have an easier time than couples with mismatched libidos.

Pick partners whose views on protection and open communication line up with your own.

And naturally, gravitate toward people you're mutually attracted to — some pairings just click more naturally than others.

Do this, and you'll spend far less energy trying to manufacture chemistry from scratch, and instead just get to build on what's already there!

Now that you understand how to cultivate sexual chemistry, you're equipped to improve your sex life or widen your dating pool. And armed with this take on sexual connection, some of you may realize what you're really after is something that has to occur naturally rather than something you can construct. Either way, you're better positioned to understand yourself, your partner, and how to tap into that electric spark in the bedroom!
