muscle cramps after sex

nearly every time my wife and I have sex, she ends up with a muscle cramp of some sort. Most of the time these cramps are in her calf or thigh (presumably from the position of her legs) but sometimes she gets them in her side or even her ankles.

Is there any way to decrease the chances of getting a cramp? or a more effective way of relieving them than just massaging them out?
