It’s totally normal and very common for people to experience body shakes post-orgasm after using a vibrator.

But, if you don’t expect your body to shake in this way, the experience can be more than a little unnerving.

In fact, uncontrollable shaking or muscle spasms and cramps can happen after orgasms that occur during partnered sex just as easily.

So, why do some of us shake after cumming with a vibrator?

Most commonly, it’s a result of releasing the built-up tension in your muscles after orgasm, but there are a few other reasons why you might shake after using your favorite vibe.

How Do Vibrators Cause Body Shaking?

How Do Vibrators Cause Body Shaking?

In the moment, it might feel like your vibrator is causing your body to shake, but the shaking is more likely the result of the orgasm your vibrator is giving you.

Body shakes or tremors are not a side effect of vibrator use; they’re caused by the orgasm itself.

Many people experience shaking post-orgasm, whether it’s a slight tremble in their legs or full body flailing.

Some partners may even find this “side effect” to be incredibly hot.

In fact, there’s a whole genre of porn videos that display people (mostly women) shaking uncontrollably after orgasm.

It’s important to know that there isn’t anything “wrong” with you if this occurs — it’s just the way your body happens to respond to arousal and orgasm during vibrator use.

“If this happens for the first time, it can be a little concerning, but it’s actually quite normal,” Dr. Susan Milstein, a human sexuality health educator on our medical review team, explained.

Shaking after orgasm can vary in duration from person to person, ranging anywhere from just a few seconds to several minutes or more.

Possible Causes

What Causes A Shaking Orgasm With A Vibrator?

Although the reasons behind each specific case of body shakes after using a vibrator will vary and there is limited scientific research available, there are a few probable causes for most cases.

[Close]
Tension
  • Release of tension:

The most likely cause of shaking after cumming with your vibrator is the sudden release of tension in your muscles.

Lots of people tense up while working toward an orgasm — think sheet or hair grabbing and toe curling.

It’s common to tense up your legs during orgasm because your thighs are the closest to your groin — right where you are clenching your pelvic floor muscles — leading to increased blood flow which then leads to increased sensation.

Some people tense up their entire body just before orgasm, resulting in even more noticeable full-body shaking upon its release.

Additionally, the position you’re in can affect how much your muscles contract, resulting in an action tremor (postural tremor).

For instance, if you’re kneeling or squatting while using your vibrator, your leg and thigh muscles are engaged to hold your position that entire time.

Once orgasm occurs and they relax, the sudden release of tension can cause them to shake — or tremor.

Increased Heart Rate
  • Increase in heart rate:

When your heart rate increases at a rapid rate, this can cause your body to shiver or tremble.

Like a fight or flight response, arousal can make our hearts beat faster to move oxygen through our bodies more quickly while giving us a boost of energy.

In the same way that you might shiver when you feel scared, a suddenly increased heart rate during arousal can make you tremble.

Nervous System Or Bodily Overload
  • Nervous system or bodily overload:

You may be shaking after an orgasm because your brain gets overwhelmed by stimulation — and your nervous system misfires.

Your body is capable of many involuntary reflexes.

One such reflex involves pulling your hand away from something hot — it happens instinctively and without thought.

Your post-coitus twitching could just be your body temporarily short-circuiting from all the pleasure signals it’s receiving at once.

Dehydration Or Nutritional Deficiences
  • Dehydration or nutritional deficiencies:

Muscles can spasm or cramp when the body is dehydrated or lacking specific nutrients, particularly magnesium, calcium, or potassium (hypokalemia).

For this reason, insufficient hydration or nutritional deficiency can result in uncontrollable muscle cramps that can cause shaking after orgasm.

As we mentioned earlier, muscles contract throughout the body, and when that tension is released during orgasm, shaking can occur afterward.

At the same time, muscle contractions may also cause cramping — which can be worsened by a lack of proper hydration or low potassium.

Such cramping can last a few seconds — or up to several minutes if severe.

Should You Be Concerned?

Should I Be Concerned About Shaking Orgasms After Using A Vibrator?

The short answer is no — not usually.

Everyone experiences orgasms differently and leg or full body shaking is a totally normal part of orgasm for many people.

That said, orgasm-induced seizures — which are not the same as simple post-orgasm body shakes — can occur in those with epilepsy, although they are very rare.

Unless you are experiencing pain or bleeding post orgasm, or experience reflex seizures as a result of epilepsy, experience a buzzing sensation in your vagina that becomes frequent or incessant, you have nothing to be concerned about if you shake after having an orgasm with a vibrator.

How To Avoid Shaking After Using A Vibrator

How To Avoid Body Shakes After Using A Vibrator

Although shaking is a very common way for a person’s body to experience orgasm, for most people, there isn’t any tried-and-true way to stop it from happening completely.

If the cause is related to hydration or nutrition, shaking and muscle spasms or cramps may be reduced by drinking lots of water and eating foods rich in magnesium (such as leafy greens) and potassium (white potatoes or bananas) regularly.

Dr. Milstein, who we spoke with earlier, advised that “if you’re having a muscle cramp as a result of dehydration,  you definitely want to address those, since they might continue even when you’re not using a vibrator.”

Another thing to consider is your body’s position as you approach or experience orgasm.

Positions that involve clenching your muscles may be more likely to cause post-orgasm shaking once their tension is released.

For instance, if you find that kneeling into a squat (which requires heavy use of your leg and thigh muscles to hold yourself upright) while using a vibrator leads to your legs shaking after orgasm, try using it while laying down, instead.

It’s important to remember, too, that body shaking after orgasming with a vibrator is common — so it’s okay to ride it out and simply enjoy it as part of the experience, as long as it isn’t uncomfortable.

Bottom Line

In Conclusion

Leg shakes or full body shakes after using your vibrator are completely normal and many people experience this.

When it comes down to it, every orgasm is different and you certainly aren’t alone in the experience.

“Shaking after sex isn’t a good indicator of how good an orgasm was,” Dr. Milstein, the human sexuality health educator from our medical review board, said. “Don’t  worry if this only happens sometimes, or happens only when you use a vibrator and not during sex with a partner.”

In the absence of existing health-related issues (such as epilepsy or nutritional deficiencies), you don’t have to be concerned if your body shakes after using a vibrator.

As we mentioned earlier, many people find it exhilarating to make their partner quiver in ecstasy — so not only is your body shaking normal, it can even be a turn-on!
