The refractory period occurs right after you reach your sexual climax.

During this brief moment, the membrane enters a refractory period that makes it insensitive to other stimuli. Objective: To prove that absolute and relative refractory periods occur as the action potential develops rather than after it ha refractory period- neuron never fire continuously.
