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?
