Body shaking after sex is a common phenomenon experienced by both men and women. It is mostly caused due to sexual arousal, orgasm, or climax. The body shaking may last for a few seconds to a few minutes and can be described as involuntary muscle contractions in various parts of the body.

4. Muscle fatigue and exhaustion from prolonged sex or physical activity,
