Muscle cramp: The most likely reason is a cramp in his abdominal muscles. This can be due to chemistry abnormalities in the blood - often due to medicines. But, it can occur with no medical abnormality. Muscle contraction occurs during sex and muscle cramps can result, just as they can with other muscles ( leg exercise, for example). If it keeps happening, then he should see his doctor.
