What is leg shake after sex?

As an AI language model, I cannot comment on personal experiences.

However, some individuals may experience leg shaking or tremors after sexual activity. This may be caused by tension and heightened arousal during sex, which can lead to muscle spasms and trembling.

In some cases, leg shaking after sex may also be a result of orgasm, as the muscles in the pelvis and legs contract and release.

It is a common phenomenon and not usually a cause for concern, but if it persists, one should consult a medical professional.
