Yeah I know that is the same feeling too. I get that before I have to talk to or work with a friend of mine.A reflection here: I had gotten into fistfights when I was a teen. There was a great andrenalin rush and then afterwards I was shaking. It often lasted an hour.
Mind you, a fistfight can ram more adrenaline into you than a coital action.
So when it gets expelled, you have the shakes.
Maybe this is what is "bothering" the people who experience this shivering. You're catching up to yourself. Recovering and getting your adrenaline level back.
