No, there isn't a way to prevent it. It's how the body is supposed to work. It's like having an urge to eat. Why would you continue to have the urge to eat after eating? Your body has gotten it's satisfaction so therefore doesn't need to make you feel like you need it anymore. Your body "rests" after finishing and "recovers" until you get the urge again.
I hope I explained it well so you can understand.
