Hello,

I am 20 years old. This is my situation when I am about to reach orgasm or when I do...

First, As I am about to reach it... usually in the position when my partner is behind me, one of my legs shake very rapidely.

Secondly, after having an orgasm my legs feel numb and sometimes, depending on the degree of intensity of the orgasm, the muscle of legs are blocked. I can't moved them and gives me pain I have to wait between 1 to 3 minutes before the spasm passes away.

Why is that?

An orgasm is not a walk in the park. It's a very intense experience. Your entire body, and especially your leg and pelvic muscles experience the effects of an orgasm first by tensing, then by totally relaxing.

That's what is happening to you.

How do you know? Have you done a survey?? It may depend on your position when you orgasm, how stressed out your muscles are before orgasm, and also the intensity of the orgasm. You may have very, very strong orgasms which could mean actual muscle pain and cramps. You also may have a low pain threshold and so feel pressure and intensity very easily and deeply.

Try other positions and see if you still experience pain.

It sounds like the muscle use in your legs from the position and the intensity of an orgasm is causing you to have muscle spasms and contractions, like a charlie horse. This could be helped by making sure you are adequately hydrated and are not low on potassium. The same thing happens to me sometimes in my calf muscles during or after sex. The contraction of the muscle would make it very difficult to move and can be very painful. I think this could be it. Hope this helps!

Could be cramps or, do you have a lower back condition? A piched nerve can do this as well and this can be serious-if your back has never been injured I'd say it is just cramping due to stress in the leg muscles.
