If you've ever felt your legs shaking after sex, then rest assured that it's a perfectly normal response to fun between the sheets. Indeed, along with rising temperatures and rosy cheeks, trembling limbs are just one of the common ways your body might respond to pleasure. 

The effects can be even more pronounced if you orgasm during sex. Because whether you've just got intimate with a partner, or have had a good time with one of the best sex toys out there, reaching climax can trigger our muscles to move in unexpected ways.

However, post-sex leg shakes won't happen to everyone. Just like what turns you on varies from person to person, so will how your body responds to some feel-good bedroom action. But, as we'll explain, it is more likely with added intensity, perhaps from one of the best app-controlled vibrators or maybe the edging technique. Here's the low-down...

Why are your legs shaking after sex?

It's important to know that leg shaking after sex is nothing to be worried about. It is usually due to having reached orgasm—and is one of the number of ways our body releases the built-up tension after intercourse as part of the “come down” experience after feeling something so euphoric. 

When we climax, we often have a physical reaction to the pleasure. This includes a heady build-up, toe-curling contractions and tingling feeling of peak relaxation. “As arousal grows, heart rate, blood pressure and breathing increase and skin becomes rosier,” says Dr Laura Vowel, therapist and principal researcher at sex therapy app Blueheart (opens in new tab)

“When an orgasm happens, the muscles in the vagina—and sometimes elsewhere in the body—often twitch or spasm," explains Dr Vowel. "At the same time, the brain releases a surge of dopamine— which triggers a feeling of pleasure—and oxytocin, the bonding or cuddling hormone.”

Tatyannah King, a sex blogger, agrees: "An intensely pleasurable release of sexual tension is accompanied by contractions of the uterus, vagina, and pelvic floor muscles. Muscles throughout the rest of the body, like in the legs, may contract as well." 

This may be heightened due to something called 'squirting'. King continues: "Some people may ejaculate when having a vaginal orgasm. When this happens, a clear fluid spurts from glands close to the urethra during intense sexual excitement or orgasm.”

So, if your legs are shaking after sex, then it's thanks to a release of post-sex tension that happens after orgasm. All that you need to do is lie back and relax...
